To summarize last year's mistakes, I shouldn't have played with small cap stocks. It hurt many brothers who trusted me. I'll be more cautious with my future sharing. I apologize for any inconvenience caused. Today, I'll talk about the precautions for copying homework.

1. Before trading, check the stock's market cap. Be cautious if it's below 100, as the risk is very high.

2. Don't just follow one person. There are many great bloggers you can copy from.

3. Don't just copy one type. For example, if you bought $NIO(NIO.US) and then bought $XPeng(XPEV.US), that's the same type. They might fall together, which is too risky. Diversify into different types, like aerospace, cryptocurrency, non-ferrous metals, AI, etc.

4. Don't go all-in on one stock. Sometimes, when you make some money, remember to take some out and don't leave it elsewhere. Some people aren't suited to having too much money in their account, as they tend to buy recklessly, always making money then losing it, losing it then making it back, busy all day for nothing. These people can't stand having a balance in their account! They wish their money could work two jobs at once.
