description: "$XL2CSOPHYNIX(07709.HK)$Micron Tech(MU.US) I recently watched &#34;Sister's Home,&#34; and the controversy between Ran Yingying and Zou Shiming gave me some thoughts: 1. Poverty-stricken couples face difficulties in everything, although not 100% accurate, when facing financial hardship, human nature is exposed; 2. Do what you are good at. Zou Shiming is a boxing champion of his generation, but that doesn't mean he can be a top performer in the boxing gym business; 3. If you venture into an area you're not good at, you must first learn and accumulate experience. Corresponding to the Buffett principle, it's &#34;don't do what you don't understand.&#34; If you really want to do it, you must first create a good MVP and can't go all in at once; 4. For my own investment thinking, money isn't spent, it's lost. The primary principle of investment is to preserve capital, preserve capital, preserve capital. Reflecting on myself, I've been losing a lot recently in semiconductors and chips. Essentially, it's still amplifying my own greed, with a high degree of speculation, and I didn't react to potential risks in time; 5. Since it has come to this, if it's a good company, a good organization, a good business model, don't look at it, it affects your mood. If not, sell it quickly, pay for your knowledge. The tuition fee is just too expensive, remember."
