When I woke up this morning, I felt refreshed and energized—it had been an especially good night’s sleep. Around 8:30, I started packing up to take Hamer to meet her classmate for some exercise. Hamer was particularly excited about the agility ladder and rings that had arrived just the day before. She’d seen others playing with them and thought they looked like a lot of fun.

When we got to the venue, we began by following video tutorials to learn footwork drills using the agility ladder. Hamer and her classmate jumped around, laughing and having a blast. Afterward, we switched to playing badminton. Hamer struggled to hit the shuttlecock and became a bit frustrated, so she set down her racket and grabbed a tennis ball instead. We decided to toss the ball to each other, trying to keep it from touching the ground. Our initial goal was 10 passes, but it proved so difficult that we lowered it to 5. When we finally achieved it, we all cheered.

Next, we experimented with catching the ball using rackets and played agility ring games, like throwing a ring and jumping to it. We took turns twice, then tried forward, backward, and side jumps. Anyone who made a mistake had to run a lap as a penalty. I ended up running twice, which had Hamer and her classmate laughing uncontrollably.

While running, I suggested a relay race, and they were thrilled. We ran three laps around the field, working well together. Despite being sweaty and exhausted, the laughter never stopped. The final game was their favorite—ring toss. Using leaves as “money” to buy rings, the two kids had a blast, laughing and jumping around. Before we knew it, it was noon, and we packed up to head home. On the way, Hamer jokingly pretended to cry, saying, “I don’t want to leave my classmate!”

After lunch, we relaxed in the living room for a while. Seeing it was nearly time for dance practice, Hamer and I began to get ready. Before leaving, I told her, “While you’re dancing, I’ll write in my journal, okay?” She found the idea novel and agreed. At the dance studio, I dropped her off and went to a nearby community study room to write. As I typed, memories of the joyful morning filled my mind, and an hour and a half flew by.

After picking up Hamer, we stopped to buy some cake. On the way, she suddenly asked, “What’s a journal?” After I explained, she said, “I want to write one too!” We agreed that next Saturday, after dance practice, we’d bring our supplies to the study room and write journals together.

When we got home, Xiaoyan was napping, so I helped Hamer with her homework. There wasn’t much to do, so she finished quickly, eating a few small cakes in the process and even taking some with her when we went out again. She wanted to join me at the hair salon, so we went together. Along the way, she chattered excitedly, saying, “I love playing with my classmate’s dad; he’s so much fun!” At the salon, I got a haircut while she had her hair washed, thoroughly enjoying the experience.

On our way back, we hurried to buy groceries. My task for the evening was to make braised noodles with green beans since I’d lost a bet with Xiaoyan over who would cook dinner on Saturday. The green beans cost 10 yuan, and the noodles 5 yuan. When Hamer heard the total price, she laughed and said, “So cheap!” I took the opportunity to explain, “That’s one of the benefits of eating at home.”

At home, Hamer spent a long time chatting on the phone with her classmate while I got busy in the kitchen. Xiaoyan stood nearby with chestnuts, occasionally feeding me bites as I worked. It had been a while since I last cooked, so I carefully followed the recipe step by step, washing, chopping, and cooking the ingredients. Though busy, I found it enjoyable. When Hamer finished her call, she came into the kitchen wanting to help, but by then I was nearly done. She stayed anyway, pretending to arrange dishes and playing the role of a restaurant server.

After an hour, the braised noodles were finally ready. Both Xiaoyan and Hamer loved them, showering me with compliments. That long-lost sense of accomplishment filled me with satisfaction.

In the evening, we lounged on cushions and the sofa in the living room, watching Klaus together while relaxing. During this time, Hamer wrote her Christmas wish list for Santa, ready for him to “collect” it. It wasn’t until 10:30 that we slowly got up to wash up and end the day.

This morning, I placed a phone playing a pinyin song beside Hamer’s pillow before leaving the room. After a while, I returned to wake her, and she slowly got up. Just as she was heading to the bathroom, she suddenly mentioned her nose was bleeding. I quickly helped her pinch her nose to stop the bleeding and assisted her to the bathroom, thinking it might have been caused by the dry overnight air. Later, I noticed her nails were quite long—perhaps she had scratched her nose and ruptured a blood vessel. I silently reminded myself to trim her nails in the evening.

While washing up and getting dressed, Hamer was extra cautious, worried her nose might not have fully stopped bleeding. She was even afraid to blow her nose when she saw mucus. Before we left, she grew anxious again, concerned there might still be traces of blood her classmates would notice. Her mood dipped, and her attitude while packing wasn’t great. We left about five minutes later than usual. She seemed bothered by the delay, but I reassured her, saying, “Today’s a special situation; it’s okay. The teacher will understand.”

After dropping her off at school, I felt unsettled on the way home, reflecting on the chaotic morning. Back at home, as I prepared breakfast and coffee, my frustration showed on my face. Once I finished, I sat down to write in my journal. As the words flowed, my mood gradually eased. Later, while getting ready for work, I noticed Xiaoyan’s expression seemed off. When I asked her what was wrong, she snapped, “So it’s okay for you to have a bad attitude, but no one else can?” I wanted to argue but decided to stay quiet.

The morning was spent addressing the spacing record issue I had discovered the night before. Despite revising it several times, there were still gaps. Thankfully, a colleague caught the problem during the Pull Request review and pointed it out; otherwise, it could have caused major issues. In the afternoon, we went out for field testing, and this time, everything went smoothly. Our first Release Candidate (RC) version was completed on schedule, marking a satisfying milestone.

Around lunchtime, on a whim, I decided to hit the gym. First, I had enough time, and second, I worried that if new issues popped up later in the day, I might miss the chance again. I packed my bag and headed out, feeling unusually cheerful. At the gym, I started with some cardio before moving on to strength training. While there, I bumped into a colleague doing heavy deadlifts. Feeling inspired, I decided to try it myself. She cautioned me, “Your back just recovered; it’s better to avoid this exercise.” Ignoring her advice, I went ahead. The weight was heavy, and after just three lifts, my lower back started to feel uncomfortable. I immediately stopped and switched to bench presses, squats, hip thrusts, and a few new machines. By the end, my arms were sore, but most of my body felt fine—except for my back, which was noticeably strained.

Close to the end of the workday, I thought I’d get home early. I called Xiaoyan and suggested we go out for Hunan noodles together. I also called Hamer and invited her along. Picking her up on my electric scooter, we met Xiaoyan near the noodle shop. By then, my lower back pain had worsened. After finishing our meal, we headed home as the night grew colder. Hamer fell asleep on the scooter, exhausted from the day. On the chilly winter night, the three of us rode home together. Xiaoyan teased me, saying, “You’re just looking for hardship—why didn’t you take the subway instead?” But as I glanced up at the sky, my mood unexpectedly lifted. The night was clear and bright, scattered with clouds, and a single shining star hung in the sky, as if guiding our way. In that moment, everything felt just fine.

Back home, Hamer stayed asleep, skipping her bedtime routine before climbing into bed. I lay flat on the floor to ease my back and ended up chatting with a colleague about ideas from our recent 1-on-1 session.

Today, I experienced “Murphy’s Law” firsthand: anything that can go wrong will go wrong, and if you’re worried about something happening, it’s even more likely. Recently, I moved a “sample interval” task on my Kanban to-do list directly into “done” without properly addressing it. As a result, during this afternoon’s testing, the related issue was uncovered—a mistake born of negligence that taught me a harsh lesson.

The day started off relatively smoothly. In the morning, we had a fairly short sprint meeting, and afterward, I continued working on the debugging issue in Visual Studio that I had left unresolved yesterday. Due to .NET version incompatibility, the debugging functionality wasn’t working properly, which had been bothering me all day. Fortunately, I managed to resolve it before noon. However, because I hadn’t controlled the variables well during testing, I’m still unsure which solution actually worked. I wasn’t willing to risk starting over to test again—time is just too precious, and the process too frustrating.

By noon, I had installed some VS plugins and even explored how to batch-install them via the command line. When I checked the time, it was already 1:30 PM, so I quickly grabbed lunch. In the afternoon, I focused on optimizing the device connection logic and made significant changes. Just as I was fully immersed in work, a colleague discovered a critical issue during testing—the very one tied to Murphy’s Law that I mentioned earlier. The overlooked details had finally caught up with me. The problem surfaced at the worst possible time, which was a bit demoralizing. I then spent most of the afternoon troubleshooting, reproducing, and fixing the issue. By the time I finished, it was already past 8 PM, and my planned gym session had to be canceled. On the way home, I did some on-site testing to verify if the problem was truly resolved, only to stumble upon another major issue. Although it was a bit of a headache, I felt somewhat relieved—it was caught early enough. After giving it some thought, I now have a rough idea of how to address it and plan to tackle it tomorrow at work.

In the evening, Xiaoyan supervised Hamer while she did her homework. Toward the later part, Hamer’s focus completely broke down—she was jumping around with Xiaoyan doing exercises, cutting small pieces of paper, and then fiddling with the mini textbooks I had brought back for her. When she only had one page of homework left, Hamer, after washing up, simply declared, “I’m not doing it anymore,” and packed up to go to bed.

Before bed, Xiaoyan and I chatted about some of the troubles she’s been having with her friends. Lately, she’s been receiving a lot of negative energy, which has left her feeling a bit overwhelmed. I listened quietly. Although I couldn’t offer much help, I hoped she felt a bit more at ease and would eventually find her own way to cope. Toward the end of the conversation, Xiaoyan suddenly brought up what happened last night—she asked what I was thinking when Hamer was walking ahead of us by herself. When I told her, “I was annoyed too,” she cut me off with, “Alright, stop talking.” She could sense that what I was about to say wasn’t what she wanted to hear. Even so, we continued the conversation. I explained my perspective and listened to hers. Although she was still a bit unhappy in the end, we managed to get everything out in the open, which was a good thing overall.

Last night, Xiaoyan had planned to continue taking Hamer to school, but by morning, she felt too tired and ultimately gave up on the idea. She decided not to go to work today, opting instead to take a day off and rest.

The morning’s work went relatively smoothly. I followed the Pomodoro rhythm to tackle tasks and maintained high efficiency. However, around noon, I impulsively upgraded Visual Studio, which led to a frustrating chain of issues. When I resumed work in the afternoon, I discovered a problem with the compiled version due to a .NET version mismatch, making debugging impossible. I tried the usual method of modifying global.json to specify the default version, but it didn’t work. Then, I installed a new SDK for VS, but that didn’t solve it either. I even reinstalled Visual Studio in an attempt to roll back to the previous version, but the issue persisted. The entire afternoon was consumed by this problem, and despite my efforts, it remained unresolved, leaving me feeling incredibly irritated.

In the meantime, I managed to complete some overdue cross-testing tasks, but that hardly made up for the time wasted on the debugging environment issues. Frustrated, I resorted to writing code on my personal computer and debugging on a test machine. Although this workflow was cumbersome, I managed to fix the remaining bugs before the end of the workday. As for the .NET problem, I had no choice but to leave it for tomorrow.

After work, I went to a café to meet Xiaoyan. She had been there in the afternoon having a meal with her colleagues. Later, we went to Hema, where Grandma and Hamer joined us. What was supposed to be a relaxed family shopping trip turned sour over a bag of chips.

Hamer wanted to buy chips, but Xiaoyan refused, worried about the health implications of eating too much junk food. This led to a back-and-forth argument between them. Xiaoyan began a lengthy lecture, starting with the health issues of chips, then moving on to our weekly shopping expenses, and even suggesting canceling next Wednesday’s shopping trip altogether. Hamer gradually lost patience, showing visible frustration and even a bit of anger. Standing on the sidelines, I couldn’t help but feel annoyed too. When Xiaoyan mentioned canceling next week’s trip, I felt it was an unreasonable remark. Since we’ve established Wednesday shopping as a regular family activity, why couldn’t we discuss and find a compromise? If we think some snacks are unhealthy or the expenses are exceeding our budget, we could set rules and adjust gradually. Flat-out rejecting someone’s choice of snack or casually proposing to cancel our routine entirely seemed unnecessary.

On the way home, Hamer walked far ahead of us, as if trying to avoid us. I also didn’t feel like making eye contact with Xiaoyan, and the atmosphere was somewhat awkward. However, as we neared home, Xiaoyan suddenly started running with Hamer, playing around, and eventually, the tension between them dissipated.

At home, Xiaoyan and I had dinner while Hamer quietly worked on her homework. After dinner, Xiaoyan did a dance workout. I watched some Korean drama before joining her, while Hamer remained focused on completing her assignments.

Today is a special day. In the morning, when the alarm went off, Xiaoyan opened her eyes. I nudged her and asked, “Are you taking Hamer to school today?” Last night before bed, she had mentioned wanting to try something different, but she hadn’t agreed to my suggestion at the time. This time, however, she got up. She woke Hamer, helped her freshen up, packed her schoolbag, and then took her to school. By 7:39, they were already at the school gate, much earlier than usual. When Xiaoyan returned home, she even made coffee for us, making the start of the day particularly warm.

Most of the daytime was spent debugging, mainly focusing on adjustments to the G feature while also quickly completing testing tasks for the mobile app. Since I didn’t use the Pomodoro timer, the work rhythm felt a bit chaotic, and it seemed like time wasn’t utilized efficiently—something I’ll need to improve on going forward.

In the evening, Hamer came home and proactively finished her homework. During a conversation, Hamer told Xiaoyan that she had been moved to the last row in class. Xiaoyan asked how she felt about it, and Hamer replied, “Not much.” Hearing this, I felt a bit anxious and initially blamed the teacher: why was she moved to the last row again? It seemed like such decisions lacked any clear rules. But on second thought, Hamer herself didn’t seem to connect this to other issues like she did last time, nor did she show any particular emotions. This helped ease my concerns a bit. I decided to observe her state first and refrain from intervening, allowing her to adapt and view the situation from her own perspective. I wondered: if we appeared overly concerned, would it make Hamer think sitting in the last row was a “bad” thing? She might even feel that sharing such small matters is burdensome, and might stop sharing them with us in the future.

Outside of today’s main plans, I spent a considerable amount of time on my blog. In the morning, I checked my email and found that the domain migration was complete. I used some time before work to configure the domain. Initially, I was a bit confused when setting up the domain records, especially with the fields “Hostname” and “Value” in the interface—they didn’t make much sense to me. However, after consulting some resources, I finally resolved the issue.

Before bed, I continued optimizing the blog, changing the theme to Alpine, which aligns better with my aesthetic preferences, and adding a few new pages. The overall framework of the blog is beginning to take shape and looks decent at first glance. Next, I plan to further optimize the pages by adding sections like TIL (Today I Learned), Journal, and Parenting, while also refining the About page. Lastly, and most importantly, I need to focus on creating more content.

This morning, Hamer woke up quite early. After asking Siri to stop her alarm, she ran over to the sofa where I was sleeping and curled up next to me for a while, mumbling sleepily, “I can’t get up.” Looking at her tired expression, I thought about how she hadn’t slept well last night. Before bed, she kept saying she “couldn’t fall asleep,” but as soon as she switched to our bed, she fell asleep almost instantly—probably exhausted from all the climbing and playing yesterday.

The morning felt long and filled with small, tedious tasks. I spent a good chunk of time updating code dependencies. Last Friday, before leaving work, I encountered an issue with the .NET environment that made compiling impossible, and I still hadn’t fully resolved it today. I need to set aside time to sort out these fundamental problems; leaving them unresolved is really dragging down productivity. While working on device management for the G feature, I initially planned a major overhaul to streamline the handling of device statuses. However, one issue after another kept cropping up. By 2 p.m., I still hadn’t made much progress, which left me feeling a bit frustrated.

For lunch, I went out and got a sandwich. As I ate, I reflected: maybe I should take things one step at a time. First, the current logic isn’t fully sorted out; second, making a big change at this stage feels a bit risky. So, I shifted my focus to handling device removal. Although the progress was limited, it gave me a small sense of stability.

I headed home a little earlier than usual in the evening and found Hamer lying on the floor doing her homework. After she read out a list of words from her teacher, we went out together to pick up Xiaoyan. After dinner, Hamer continued working on her assignments. I stayed with her and helped guide her through the remaining tasks. By the time we were done, I felt like my day was complete and wasn’t motivated to do much else. I idly scrolled through my phone, watched a bit of TV, washed the dinner dishes, and replaced the filter in the water purifier. After wrapping up these small chores, I was pretty tired myself and headed to bed early for some rest.

I woke up before 6 a.m. today. Though I couldn’t fall back asleep, I didn’t get up right away. Instead, I stayed in bed scrolling through my phone and came across a thought-provoking comment on Zhihu about “removing primary school-level education from kindergarten.” One part of the comment really struck me:

“Hiring graduates from prestigious universities like 985 and 211 schools doesn’t even require offering a high salary or using manipulative motivation tactics; just pile the work on them. The dedication to progress, sense of responsibility, and meritocratic values instilled by the education system will naturally push them to invest time and get things done—working overtime if necessary. They can’t help themselves.”

This sentiment captured exactly how I’ve been feeling lately. Last night, after playing badminton, I gave a colleague a ride on my e-bike, and he remarked, “I’m barely into my job here, and I’ve already seen such intense overtime.” I couldn’t help but wonder: if I don’t throw myself completely into this, how should I approach situations like this?

After I got up, Hamer also got up on her own, washed up, and got dressed. She was moving slowly, but today I didn’t urge her on. When we were leaving, she insisted on bringing an umbrella. We searched for a while but couldn’t find the one she wanted. I handed her an umbrella that she had decorated herself before, but she didn’t want to risk getting it wet. In the end, we decided not to use an umbrella and rode the e-bike through the drizzle.

The light rain continued throughout the day, and when I got home in the evening, it was still falling, which disrupted our plans to play badminton. Hamei was a little disappointed, so instead, I played with her at home for a while. Looking over her school log, I noticed she didn’t have too many tasks. But when it came time to review math, she was visibly reluctant and seemed irritable, though I couldn’t figure out exactly why.

As it was almost time to go shopping, I told her to get changed. Unexpectedly, she kept changing her clothes several times until she was satisfied. Then, while looking for her socks, she couldn’t find the pair she’d just taken off, which made her frustrated. Watching her impatiently search from the doorway, I asked, “Is there another way? Maybe you could check one item at a time, or put on a different pair, or even go without socks?” But she stubbornly insisted on finding the exact pair she’d taken off and wouldn’t look on her own; she grew increasingly upset and started crying.

I didn’t help her and stood by, feeling a bit annoyed myself. Then she got angry at me, picked up her grandma’s phone, and called Xiaoyan to complain, telling her she didn’t want to go to Hema with me. Xiaoyan patiently comforted her and suggested she could walk there by herself with an umbrella. Hamer immediately brightened up at this idea. After finding her socks with grandma’s help, she picked up the umbrella and dashed out the door without a backward glance.

On the way, she walked along the sidewalk while I rode my e-bike in the adjacent bike lane. At one point, she even jogged alongside me with a slight look of determination on her face. Watching her run like that made me feel a mix of amusement and relief. When we arrived at Hema, her mood had mostly settled. Though she still mentioned being “mad” at me, it was clear she was feeling much better.

Back at home, Xiaoyan and I ate dinner while Hamer practiced her eye exercises, and then she reviewed her math lessons.

The workload today was relatively light; most of it involved following up on recent changes to the RT module and compiling a list of technical points worth studying in depth. I spent quite a bit of the afternoon troubleshooting an issue with S123 authentication. I couldn’t make any headway until a colleague informed me that the version I was using didn’t yet include the necessary hotfix.

In the evening, I didn’t do anything particularly noteworthy. I applied for an Apple account for Hamer, removed a few categories from my blog only to realize that some articles were no longer visible as a result, and followed up on some questions regarding domain migration. There wasn’t much that felt especially fulfilling, and by the time it reached past eleven, I ended the day feeling a bit unsatisfied.

In the morning, Hamer was moving a bit slowly. When I saw that it was already close to 7:40 and she was still leisurely getting dressed, I started feeling a bit frustrated and couldn’t help but raise my voice, reminding her, “What about your jacket? Your water bottle? Your hat?” In my impatience, I didn’t properly respond when, on her way down the stairs, she said, “I’m still afraid of language class.” I knew she felt nervous about it, but in my rush, I brushed off her feelings, and that left me feeling a bit guilty throughout the morning.

After playing badminton this evening, I bought her a small chocolate as a token of apology, though I didn’t say anything about my intention. Before bed, I talked with Hamer about her fear of language class. Our conversation seemed to bring her some comfort. I shared with her my impression of the language teacher from the last parent-teacher meeting, telling her I found the teacher quite strict—even I felt she was hard to deal with, so it’s only natural for kids to feel intimidated. I also mentioned that last month, when we visited Ms. Yang, her language teacher made a point of complimenting her performance, letting her know that the teacher values and acknowledges her. Hamer, too, shared a moment when the teacher seemed warm—she’d gone up to the teacher with a piece of paper, and the teacher, smiling, asked her, “Got it now?” Hamer had smiled shyly back. This small interaction seemed to ease her a lot. We also chatted briefly about her P.E. teacher, and she laughed, saying he’s quite funny, always jokingly calling her by her full name, “Yi·Duan’er.”

When I woke up this morning, I remembered her mention of language class and realized she’d been learning initials and finals in pinyin lately. So I found some resources on Spotify for her and played them as she got ready. I hoped the audio would help her feel a bit more familiar with the material. For breakfast, we tried a new type of mini corn we’d bought. Though small, the kernels were plump and tasted great. I also took a cup of coffee to work in the new mug Xiaoyan had bought.

At work, I continued focusing on the development of the “G” feature. I spent a good part of the morning debugging an issue with chart display, eventually discovering that the Y-axis scale’s reserved space was causing gaps. After lunch, I didn’t take a break and used the time to fully resolve the issue. Then, I organized the state display for locations, constantly refining it to consider every possible scenario. Before I knew it, the entire afternoon had flown by, and I was actually a bit rushed to make it to badminton.

When I got home that evening, Xiaoyan and Hamer were doing an exercise routine together. After dinner, I helped Hamer with her homework, which wasn’t as heavy as the previous days. Once she finished washing up, she didn’t rush to bed. Instead, she quietly sat and focused on coloring her My Melody picture. We gently reminded her, “Try to go to bed earlier, or you won’t be able to get up tomorrow.” She replied casually, “Then I just won’t get up.” Xiaoyan and I couldn’t help but laugh, deciding not to push her any further and let her go at her own pace. Maybe sometimes it’s okay to let her make her own decisions—she’s right, after all. If she can’t get up, then she can’t get up.

Today is Dad’s birthday. The family prepared a table full of delicious dishes, and my uncle, grandmother, and sister all came over. They had dinner together, with a birthday cake to celebrate. It was lively and warm.

This Monday was busy as usual, but it felt productive and reassuring, like everything was back on track. While going through this week’s tasks in the morning, I realized there were fewer urgent things to handle, which was a relief. I could tackle things one by one at a steady pace. My primary focus during the day was still on developing the GNSS functionality, and today I concentrated on the Geodatabase data processing section. I resolved an issue where altitude was missing during playback, added several customizable fields for users, and also addressed conflicts with other features. One small issue after another was sorted out, and productivity was good.

In the morning, Hamer seemed a bit sleepy, and I was too—it was a tiring day yesterday, plus she stayed up late finishing homework. We didn’t take the e-bike today; as we were about to leave, I realized I had forgotten both my phone and wallet, so we ended up walking to school together.

On my way to work, Xiaoyan sneakily slipped an orange into my hat. I didn’t realize until I was in the elevator at the office, feeling something pressing against my head—only then did I discover her little “prank.” Such a mischievous one! Shortly after, the Starbucks coffee cup she secretly bought for me a few days ago was delivered. It feels nice to hold, and the size is perfect. Recently, Xiaoyan has bought me quite a few things—just this morning, I received a pair of jeans she bought last night. A few days ago, she got me a sweatshirt, sweater, and down jacket, practically setting me up for the whole winter. My attitude toward her shopping for me has also changed; now, I’m happy to wear whatever she picks out, which is a shift from my earlier resistance. Xiaoyan was a bit surprised by this, as I used to feel it wasn’t necessary to spend so much on clothes and preferred to choose my own.

Today, I left work on time and went home with Xiaoyan. Hamer got a head start on her homework today, so by the time we got back to help her, there were only a few parts she found challenging. We went through her tasks one by one based on her log, finishing up around 9:30 p.m. Toward the end, I suggested using a Pomodoro timer to help her manage her time, so she could have breaks between tasks. During each break, she and Xiaoyan would do some exercise together—she’s taken quite a liking to this recently, finding it both fun and relaxing.

This morning, the alarm went off around 7, and I was still feeling quite groggy. For a moment, I even considered telling Hamer that maybe we shouldn’t go to Fragrant Hills today. But before long, I got up and went to check on her room. She was already awake and even laughed, saying, “I saw you were still asleep, so I didn’t wake you.” After we washed up, we bundled up in warm clothes and headed out.

We grabbed breakfast at 7-11, where Hamer tried a rice ball and thought it was particularly tasty. She took a few bites of the chocolate donut she’d picked but soon focused on the rice ball instead. The sky was overcast, with heavy smog, and as we ate, it even started drizzling.

We took the subway to Fragrant Hills, and when we transferred to the Xijiao Transit Line, we discovered it was a unique two-car tram, which was pretty interesting. Once we arrived at Fragrant Hills, the first thing we saw was a lively shopping street. Hamer immediately had her eye on Mixue Bingcheng and candied hawthorn skewers, so we agreed to pick some up after our hike. Even before entering the park, we could already see some red leaves, but once inside, we realized the foliage wasn’t as widespread as we’d imagined—patches of yellow smoke trees, ginkgo, and maples dotted the path here and there.

We entered from the east gate and took the central route up the mountain. Although Hamer got a bit tired, she never once said she didn’t want to climb or asked me to carry her. At first, we took breaks fairly often, rehydrating and snacking each time. Gradually, the weather cleared, the sun came out, and the air warmed up quite a bit. At one point, we came across a small side path and, seeing others on it, decided to explore it like an adventure.

The path started as grass but soon turned into a steep, slippery mix of dirt and rocks. Hamer climbed carefully but determinedly, and as I watched her from behind, I felt a swell of pride. About halfway up, we looked back and realized this path was both long and steep—we had unknowingly taken Fragrant Hills’ hardest trail on the north side.

At last, we reached the summit and rested for a good while. Hamer happily played on the steps, using them like a slide over and over. She had an ice cream too. Earlier, she’d worried that if she had ice cream, she might have to skip the candied hawthorn skewers, and she even offered to give them up. I laughed and said, “You climbed all the way up here; of course, you deserve a reward! Let’s both enjoy them!” She happily dug into her ice cream, her face lit up with a look of pure contentment.

The descent was much easier, but we made it more interesting by picking two side trails as our “bonus challenge.” Both were rough, and we ended up covered in mud, but it added to the fun. Back at the base, we kept our promise—enjoyed candied hawthorn skewers and Mixue Bingcheng drinks—and then took the subway home.

The whole way back, Hamer was eager to get home to play with her aunt. After confirming that her aunt was at home, she showered quickly and dashed off to find her. That evening, after they returned for dinner, I asked her aunt to join us for Hamer’s homework session, which lasted from 7:30 to a little past 9.

This morning, Hamer got up relatively early. I called her once, and she didn’t linger in bed—she got up promptly.

During the day, I continued focusing on GNSS development, mainly working on implementing the new UI design, organizing the logic, and fixing various bugs. The deeper I got, the more I realized how many details needed careful handling. My colleague finished the workspace section today, and another colleague completed the elevation change chart. Practically everyone on the team has been involved in some aspect of this big feature, which makes me both grateful and a bit humbled by the collaborative effort.

In the evening, on the way to go shopping with Hamer, we talked about her day at school. She mentioned that her Chinese teacher had given her a “Good Job Ticket” as a reward. I asked her, “Did you feel sleepy in class today?” She shook her head, saying she didn’t. Then I asked, “So do you think it was worth it to stay up so late working hard on your homework last night?” She looked puzzled and asked, “What does ‘worth it’ mean?” Not sure how to explain it simply, I rephrased, “If you could choose again, would you still stay up late working hard on your homework?” Without a moment’s hesitation, she replied, “Of course! I want to get my homework done.” Her resolute tone filled me with admiration.

We met up with Xiaoyan at Hema, and after finishing our shopping, Xiaoyan took Hamer home while I went back to the office to put in a bit more work. I needed to merge a pending PR and wanted to address some unit conversion and I18N issues on the dashboard. I stayed until about 10 PM before heading home.

When I arrived home, Hamer was already asleep. Xiaoyan told me that earlier, Hamer had said to her, “Our Moral and Society teacher said elementary school students should get 10 hours of sleep every day.” So by 9 PM, Hamer had stopped everything she was doing, including the workbook she was so diligently working on yesterday, went to wash up, and went to bed. Xiaoyan relayed this with a bit of humor, amused by how closely Hamer follows her teacher’s advice and this display of “self-discipline.” Later in the evening, I asked Xiaoyan if she was feeling down, as she’d seemed a bit distracted while shopping, almost lost in thought. She told me she wasn’t exactly unhappy, just a bit disheartened because work hadn’t been going smoothly. She felt that her overseas project wasn’t being given enough attention within the company, and that was starting to make her feel somewhat unappreciated.

There was something I forgot to record yesterday, mainly a conversation Hamer and I had about how to interact with friends and how to view appearance (ideas of beauty and ugliness). These are concepts she’ll need time to understand gradually, and they’re topics I want to keep discussing with her to help her grow and better understand these things.

This morning, I woke up at 4:30 AM, my mind filled with thoughts about GPS devices, and I just couldn’t get back to sleep. So, I opened Taobao and started browsing for devices, spending almost an hour researching how to properly install a GPS module that could be connected directly via USB. After getting out of bed, an email in my inbox titled “GPS Data Formats: An Introduction to NMEA Format” caught my attention. I then checked out a project called GPS.Net on GitHub, finding detailed implementations on device connectivity, which I plan to dive into more deeply another day.

Hamer was a bit reluctant to get up this morning and arrived at school slightly later than usual. Last night, she stayed up a bit late enthusiastically practicing with her workbook, so she seemed a bit tired in the morning.

My day wasn’t particularly eventful. I spent most of the morning in meetings, and the afternoon was dedicated to handling a few relatively straightforward tasks. Around noon, I had an early lunch and took a short nap. Although my body felt somewhat refreshed upon waking, I still didn’t feel fully rested, as if my body was signaling a need for more sleep.

After playing badminton in the evening, I returned home and had dinner. Around 8 PM, Hamer and I sat down together to do her homework. She had an especially heavy workload today, including pages from 5·3 Daily Practice. The teacher had asked them to bring it to school tomorrow, suggesting they complete a full 33 pages. Since she had only done a few pages before, tonight’s task was a daunting one. Yet, I was impressed by her determination—she was eager to finish it all. From 8 PM, she kept at it until now, which is already 11:56 PM, with 10 pages left to go. Both Xiaoyan and I tried to persuade her to go to bed, but she stubbornly insisted on continuing. Her dedication is both heartwarming and admirable.

While helping Hamer with her homework, I also learned something new: holistic reading syllables. These are syllables that maintain the same pronunciation even when a vowel or a consonant is added. There are 16 such syllables: zhi, chi, shi, ri, zi, ci, si, yi, wu, yu, ye, yue, yuan, yin, yun, and ying.
