【2026-03-07】Watching the frenzy around Tencent Tower installing OpenClaw today gave me a lot to think about. Many big tech companies are aggressively pushing non-technical frontline employees to install this AI tool, with some even offering 500 RMB door-to-door installation services. Everyone's desperately searching for use cases, demanding implementation, and trying to prove this thing is too important to miss. The whole process gives me a strong sense of cyber-tech folding.

As Bitcoin dropped from its $120k peak to around $70k, panic swept through the market once again. During previous major stock market crashes.

【2025-07-17】A simple sharing within the team, I took some time on the weekend to sort it out and talk about how engineers can invest better. Since buying US stocks is very risky, I don't recommend that you follow it. You need to have your own judgment. Just treat it as me talking nonsense and take a casual look.

【2025-07-09】For a user who has been using an iPhone for more than ten years, I switched to Android for about a month. I chose an OPPO device. The migration cost was much smaller than I imagined, and who would have thought that Android would become my main phone. I want to chat with everyone about the changes in my thoughts during this process.

【2025-01-30】I'm used to taking advantage of the quieter days during the Spring Festival to reflect on the past year. If I had to choose a keyword for 2024, it would be "continuous iteration." I'm increasingly realizing that everyone's most important project is actually themselves. Your life experiences, personality, values, and skills constitute this project, and it needs continuous refinement. This summary marks the end of 2024 and the beginning of version 2025.
