1. How to buy a fund: Bring my ID card to the nearest securities company's business department or state-owned bank's business department, and you can buy and sell the fund after opening an account.

2. Is it possible to put it there after buying it? The fund is known as expert financial management, and it will take a long time to know the management level and ability of the fund.

3. Suggestion: If you don't know anything about financial transactions, you'd better buy an index fund and hold it for two years.
