【2026-03-12】I'm sharing what I've learned from six months of using Claude Code across two accounts. It covers context management, Skills, Hooks, Subagents, prompt caching, and CLAUDE.md design, with a focus on making collaboration more reliable and easier to control and check.

【2026-03-07】Watching people flock to Tencent Tower to get OpenClaw installed today gave me a lot to think about. Many big tech companies are aggressively pushing non-technical frontline employees to install this AI tool, and I've even seen people online offering home installation for 500 RMB. Everyone's desperately searching for uses for it, demanding results, and trying to prove this thing is too important to miss. The whole thing feels like people living in different technological worlds, folded into the same place.

【2026-02-01】When Bitcoin falls, it becomes easier to distinguish between the casino and the cathedral. As Bitcoin dropped from its $120k peak to around $70k, panic swept through the market once again. During previous major stock market crashes. Price volatility is the casino's noise, while what truly determines long-term returns are those cathedrals that require a century of devotion yet continuously create structural value.

【2026-01-24】Last week, while shopping for New Year's Eve gifts for my team, I casually asked on X what the most satisfying purchase people made in the past year was. I received 243 responses, discovering countless great products ranging from essential tech to practical everyday items.

【2025-12-22】Recently, I shared "Breakthrough and Development of the Next Generation of Engineers - Practical Transformation from Position to Capability" at AICon in Beijing. I have converted the PPT into images and posted them here, looking forward to exchanging ideas with you.

【2025-08-17】After using Claude Code for less than a month and spending $326 (actually $20 for Pro + $50 for top-up), the Cursor I had been using for a few months has become obsolete. Using AI well can easily help you reach the level of a senior engineer. As an engineer, I feel both amazed and concerned.

【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.

【2024-10-13】I recently finished reading "Don't Trust Your Gut: Use Data to Get the Life You Want." It's a relatively simple and easy read—you can finish it in an afternoon. It covers topics you might encounter in life, such as love and marriage, parenting, wealth, entrepreneurship, luck, appearance, happiness, and pain.

【2024-09-09】This is a recent sharing within the team, based on my own understanding of AI, investment, and next-generation technologies, combined with reports, materials, papers, financial reports, etc. from the internet. If you don't understand some terms, you can ask GPT. I hope you enjoy it, but please don't invest based on this without understanding the market, as the risks are very high.
