【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.

【2024-06-30】I recently finished reading "Stepping Inside - The Chinese Government and Economic Development". I had a quick read last year, and recently, while it was raining continuously in Hangzhou, I stayed at home listening to the rain and reading, which was very pleasant. It's a good book that's worth reading twice. I spent some time transcribing some good points for future reference.

【2024-05-08】A man's happiness can be simple. I actually went back to wired headphones. I spent some time on weekends trying out a lot of good headphones offline, and surprisingly ended up buying these Sony MV1 open-back monitor headphones. They don't have noise cancellation and are wired, but I love them. I want to share my selection process with you all.
