1. Bank channel: I can use my ID card to open a personal debit card and a fund account at the bank counter, so that I can buy funds, either at the counter or through self-service channels such as online banking. There will be a discount on the handling fee of the self-service channel, generally 20%, which will eventually be around 1.2%. Open-end funds can only be purchased through bank channels.

2. Brokerage channel: I hold my ID card to the securities business department to open a shareholder card, open a fund account, and open the stock or fund trading function. I choose a commonly used bank to pre-designate the three-way depository, open a personal debit card in the bank, sign a three-way depository related agreement, and then I can buy and sell funds or stocks. Brokerage channels can buy closed-end funds or open-end funds, and some brokers have lower fees.
