1. Use software for screening, such as Tian Tian Fund Network or Chen Xing Network. The software can be used for star screening, industry screening and fund category screening.

2. After preliminary screening, you can choose a fund company or fund manager. Generally, large fund companies and fund managers with outstanding past performance and more than 5 years' experience should be selected.

3. If you make a fixed investment in the fund, you can choose a fund with relatively high volatility. If you can't take risks, you can choose a fund with a smaller maximum withdrawal.
