I woke to peaceful birdsong and made fruit for breakfast, though Hamer didn’t eat much—her appetite’s been low lately. Still, eating at home gave us some relaxed morning time together.

I spent the day focused on tool migration, deepening my understanding of chat history and function parameter handling for future plugin work. Unfortunately, I got stuck debugging and couldn’t leave work early.

At noon, I trained legs at the gym for the upcoming marathon. Feeling worn out by evening, I took Hamer shopping, and we ended the day quietly by the river, enjoying the breeze.

On 5·20, I surprised Xiaoyan with Starbucks breakfast, though her initial reaction to the price left me slightly deflated.

The morning was filled with meetings, and in the afternoon, I focused on refining a Semantic Kernel plugin to return schema-compliant data—finding the key clue in a past chat history.

Beijing was hot; I played pingpong at noon, badminton in the evening, and jumped rope with Hamer at night. She struggled with a new move and got frustrated, but with patience, she made progress and smiled.

A small morning conflict with Xiaoyan left me feeling distant, though we briefly discussed it before leaving home.

At work, I finalized the YAML-based message scheme for frontend-backend integration with ChatGPT’s help—a satisfying milestone after days of planning.

An unproductive summer event meeting was followed by urgent bug fixing and preparing materials for tomorrow, which delayed me until after 7 p.m., forcing me to skip my run.

For dinner, we enjoyed crayfish sent from Hunan. Hamer especially loved it, happily peeling and eating with oily hands, though we were all overstuffed by the end.

After a restful morning, I tested life-in-weeks and running-page for my blog setup. Before noon, Hamer and I visited a nearby park—she drew while we snacked in the shade, enjoying a quiet, peaceful moment.

In the afternoon, we watched The Lament of Qu Yuan. The performance was moving, especially in the later scenes, and both Hamer and Grandma were brought to tears.

Before the show, we briefly met Xiaoyan, who was busy guiding Australian clients. We ended the day with a warm dinner together, wrapping up a beautifully full day.

I slept in until late and felt much better physically—less soreness and more relaxed. 

At noon, Xiaoyan and Wanna came home, and we enjoyed a delicious lunch. Hamer went to dance class while I played soccer. Though we lost 2–4 against a strong team, it was an intense and enjoyable match.

Afterward, I practiced piano and made progress coordinating both hands. Xiaoyan and Wanna took Hamer to get new glasses.

This morning, Xiaoyan left early for a work trip to Shanxi. After dropping Hamer at school, I reviewed AI + GIS news and discovered a great new workflow—summarizing curated links via ChatGPT.

Our sprint meeting revealed scattered progress, prompting thoughts about improving team cohesion by merging separate meetings. Most of my day went into documentation, including our weekly summary and an MVP draft.

In the evening, I helped Hamer with homework—she was cheerful and focused. We walked, picked up snacks, and she later surprised me by drawing a girl in a foldable ballet dress, staying creatively immersed until late.

I took the afternoon off to attend Hamer’s first parent-teacher meeting of the year. Before that, we played together and enjoyed tripe soup—Hamer loved it and nearly finished her own bowl. The meeting was insightful, especially a heartfelt speech from another parent that left me inspired.

In the evening, we relaxed as a family by the river.

In the morning, I studied Semantic Kernel plugin development, applied some best practices, and optimized plugin logic. DeepWiki helped me better understand the docs, and I began using Mermaid for clearer diagrams.

A light rain and thunder started the day, but Hamer’s cheerful breakfast from 7-Eleven lifted our mood. By noon, the sky cleared, and I went to the gym for leg training—sweaty but rewarding. I listened to a podcast about parents using exaggerated praise to boost kids’ emotional value, which I might try with Hamer.

In the evening, our family relaxed by the river with snacks and a makeshift shoebox table. Hamer and I ran and played while Xiaoyan rested.

At work, I designed the AI Chat backend and integrated the build process into Jenkins to improve team efficiency.

I spent the day diving into CefSharp’s JavaScript Binding and successfully ran a sample using the new registration method. Noticing a mistake in the official docs, I updated the Wiki and submitted a PR to fix it—my second accepted contribution to the project, marking a small step into open source.

After badminton in the evening, I rode my e-bike to meet my classmate. A heavy storm hit just as I arrived at the wrong hotel—lucky timing. We chatted over dinner, waited out the hailstorm, and I rode home once the rain stopped around 9:50 p.m.

After work, I took Xiaoyan and Hamer to sit by the river, a spontaneous idea born during yesterday’s run. We brought fruit and chairs, chatted in the breeze, and later enjoyed hot ramen together—it was a short outing, but deeply fulfilling.

In the morning, I woke up sore from recent workouts and considered focusing on leg strength for marathon prep.

At work, after a meeting, I studied JavaScript Binding in CefSharp.

It was a full and joyful day. In the morning, our family visited museums separately—Xiaoyan took Hamer to the Science Museum, while I explored a traditional Chinese medicine exhibit with Grandma.

In the afternoon, I visited the Archaeology Museum and was impressed by the immersive cave-like design and bilingual display quality.

In the evening, I unexpectedly ran 10 km, plus a 1 km sprint, while listening to The Art of Loving by the riverside.
Before bed, Xiaoyan and I had a rare, meaningful conversation about future plans—something we hadn’t done peacefully in a long time.

I woke up early and suddenly decided to rearrange the bedroom layout to reuse our old wardrobe. Spent the morning reorganizing, including tidying up the small room. Hamer loved the new setup and rushed to try out her bed.

After lunch, everyone went their separate ways—Xiaoyan to a dental appointment, Hamer to dance class with Grandma, and I went to play soccer. The game lacked energy, but I chatted a bit with teammates on the subway ride home.

Later, I met Xiaoyan and Hamer in Sanlitun, hung out with Hamer for a while, and saw a confident little girl climbing impressively, which left a strong impression.

It was a rainy day in Beijing. I dropped Hamer off at school with just one raincoat—she ran in through the rain, which made me feel a bit guilty. Xiaoyan and I commuted together, and during breakfast, we had a brief disagreement about the messy house.

At lunch, I squeezed in a light gym session.

Work was smooth: I finalized the AI newsletter and joined a productive meeting where a collegue shared a flexible new framework for the AI Assistant. I spent the evening debugging an MCP tool issue, finally resolving it by 8 p.m. before heading home exhausted.

Today felt like an emotional roller coaster—starting with anxiety in the early morning, turning into worry later in the morning, followed by a glimmer of progress around noon, sinking into helplessness in the afternoon, and finally ending with relief in the evening. All of this was triggered by a technical presentation I wasn’t prepared for. … I was about to head out but figured I might as well sit in and listen to the CoP meeting to get a feel for its format and vibe. After some quick greetings, the sharing session began. The presenter’s slides were polished and their delivery was smooth. It made me a bit nervous about my own future presentation—my content is still incomplete, some parts borrow other people’s ideas, and my slide design is fairly plain.

Last night, Xiaoyan came home very late because of a flight delay and woke me with the doorbell.

This morning, Hamer anxiously asked whether she needed to rewrite her math assignment, only to learn that she just needed to make corrections—yet she still has to redo it fully this evening.

During my commute, I admired colorful blooms and used ChatGPT for flower identification. It provided a more accurate and detailed result than the now-retired Flower Recognition app.

I spent the day preparing my MCP presentation, generating new flowcharts from the spec and code, and planning to polish and map out the demos and Q&A.

After work, I arrived home early and finalized Hamer’s statistics report, though she insisted that Mom help instead because she finds me “nitpicky.”

Returning to work after the Labour Holiday, I spent the morning helping Hamer decide on a topic for her statistics assignment—she ultimately chose to map sports courts and player numbers. By bedtime, she had sketched out her layout and is ready to colour it tomorrow. I also outlined my upcoming MCP presentation and found more substance than I had expected.

Today, I spent a make-up workday testing our MCP server using Cherry Studio and SiliconFlow instead of Claude Desktop, and refactored poorly structured parameters into typed classes. Despite steady progress, I missed my usual excitement when tests didn’t yield expected results.

In the evening, Xiaoyan’s friend joined us for a Brazil-themed dinner, and Hamer dove into her new extracurricular books—she even picked one up on her own, which made me quietly proud.

Overall, I felt tired and a bit unmotivated, but reminded myself it’s okay to take things at a slower pace sometimes.

Hamer started her day by building a tiny notebook and sharpening a pencil to match. After breakfast, we returned to Tianqiao Theater for Into Ballet, arriving early to join the introduction part and waiting for a while at the backstage send-off after the performance.

Following a quick lunch, I headed to a soccer match—playing goalkeeper and leading a thrilling late comeback—while Xiaoyan took Hamer to ballet and a dental appointment. Later, we reunited at a riverside café with live music and helped rescue a mandarin duck from aggressive peers using orange peels.

In the evening, we relaxed for two hours at Liuliu’s dad’s barbershop, where we all got fresh haircuts and enjoyed the lively chatter.

Xiaoyan dropped Hamer at school before leaving for Handan on a business trip.

At work, I completed a major cleanup of our MCP server projects—adding tests, updating pyproject.toml, managing dependencies, and refreshing READMEs—wrapping it up by 8 p.m.

In the evening, I briefly reviewed Hamer’s math homework. She delighted in role-playing as the teacher and reading her Chinese characters aloud. Later, she practiced the Rubik’s cube—her finger movements growing more confident—even as sleepiness soon set in.

Tonight was my first real attempt this year to help Hamer with her homework. She pointed three enhancements after my requesting: no asking her to explain answers, no interrupting her snacks, and she’d prefer Mom help instead.

Her teacher had shared extra exercises and called to discuss her struggles—rushing through problems, getting distracted, or not fully grasping concepts. It made me realize I need to be more involved in her learning going forward.

In the morning, Xiaoyan took Hamer to school. Hamer joked, “Do you even know where my school is?”—a funny moment between them.

At work, I focused on MCP transport types, explored uv, and began organizing the project for long-term maintenance. Slow but satisfying progress.

This morning’s meeting felt dull—low energy all around, and I wasn’t in top form either. I hate feeling that way but haven’t figured out how to fix it yet.

I continued refining the MCP server based on ArcGIS Portal Service, uncovering more subtle issues as I went.

In the afternoon, I had the next stage of my root canal—cavity filling and crown prep. Thankfully, it wasn’t painful.

Evening was spent fixing Xiaoyan’s Line account. After trying and failing to recover it with a temporary number from sms-man, we had to start fresh—meaning re-adding all her contacts.

On the tech front, I signed up for WildCard, activated Anthropic’s API, and tested Claude Code. With Gemini available via Google AI Studio, I’ll hold off for now. Next up: exploring the llm CLI tool with its Gemini and Anthropic plugins. Looking forward to diving deeper.

I woke up early and dove back into the official MCP docs—so well written that re-reading them sparked new insights. It helped me refine some lingering thoughts from yesterday’s discussion, giving me more clarity moving forward.

The morning was filled with meetings. Our usual weekly session felt oddly quiet with few attendees, but the room filled quickly for Zhongzhi’s presentation on supplemental medical insurance—a stark contrast.

Before lunch, there is an update on the UC planning, maybe there still a chance.

In the afternoon, I focused on the Portal Service MCP server using Cursor and Claude 3.7 Sonnet. But this time, the generated results didn’t click. I spent hours debugging with little progress. It made me think: maybe it’s time to go back to basics and handwrite the logic based on the docs for deeper understanding.

After work, I joined a relaxed basketball session. No hard running, just fluid movement. It felt great—no back pain this time.

And yes, the Rubik’s cube craze is still going strong—I solved it in the bathroom, during my ping-pong break, while walking, resting, and again after getting home. Each solve is faster and smoother. It’s become my steady little ritual throughout the day.

Today, I felt deeply immersed in my own world, until my colleague came by in the evening to discuss some MCP-related matters. Although I didn’t have all the answers, our conversation clarified many things I want to explore with MCP. I felt like I had broken out of a closed-off state. When I later worked on the AI news, I found myself reenergized.

In the morning, I stuck to my plan and made steady progress, but by the afternoon, my energy dipped. I wasn’t sure if it was due to poor sleep or the slow performance of the local model, which started to frustrate me.

Throughout the day, I became completely absorbed in solving the Rubik’s cube. I practiced while waiting for Xiaoyan, during my midday walk, at lunch, back at the office, waiting at traffic lights, and even after dinner. The Rubik’s cube was my constant companion today.

This morning, Hamer and I headed out to watch the Beijing Half Marathon. She was fascinated by the huge crowd of runners, and we stayed until the 8km cut-off point.

Craving lamb offal soup, we went to Xiaoguan Market. Hamer curiously tried my lamb tripe and ended up eating the entire extra portion I had ordered.

At home, I practiced solving the Rubik’s Cube, following a tutorial. Xiaoyan tried to nap beside me while I made clicking sounds—she was not thrilled. Later, she took Hamer to a café with her math homework. They also discovered a massive playground near Side Park—definitely worth a revisit.

I kept practicing the Cube and finally solved it around 3 p.m.—an exciting moment. I continued practicing until I got faster, then watched a Korean drama that was underwhelming but passable. By night, I felt mentally drained and didn’t want to start anything new.

It was a vibrant Saturday.

We started the day with the Beijing Half Marathon Family Run, completing the 2km race hand in hand. After enjoying generous race packs and a relaxing brunch, Xiaoyan and Hamer went to dance class while I played goalie at football—earning praise for some solid saves.

Later, we explored Sanlitun, talked about DIY doll-making, drank in a riverside bar, had some late-night noodles, and enjoyed Reply 1988 together before bed.
