There are several ways to buy a fund: one is to buy it at the bank counter, as long as there is a bank card, the handling fee is1.5%; The other is to buy in online banking, you need to go to the bank to handle it, you can buy and sell the fund yourself, and the handling fee is 6-8 fold. The third is to buy on the fund company's website, but also to open online banking, the minimum handling fee is 60% off. Another way is to buy in a securities company. There are two situations here. One is ETF funds like stocks, which are traded on the stock exchange like stocks. The other is to buy funds at securities companies, which is basically the same as buying funds at bank counters, and it is also a handling fee of 1.5%. You also need to open a trading fund account in the securities trading system. I don't know what kind you are talking about.
