1. The fund account you opened in the bank. You can use this fund account to buy funds in the bank, or you can use online banking to buy funds on the bank's website.

2. To apply for a fund in a fund company, you have two accounts. An account is an account of a fund company, which is registered and managed by a fund company, while Deng Zhong TA account is a fund registered and managed by a Deng Zhong company, usually an LOF fund, which can be an open-end fund or traded in the stock market, that is, traded in a securities company.

According to your supplement, I will make a supplementary answer:

1. Your first and second points are basically correct. I would like to add that the bank's fund account can only be used when the corresponding bank or its website purchases funds. For example, ABC's fund account number can be used when purchasing funds at ABC's counter or on ABC's website. The account number of the fund company can only be used when purchasing funds on the fund website.

The third point is wrong. Let me explain: Under normal circumstances, only one corresponding fund can be purchased for the account of Deng Zhong Fund. For example, I have two Guangfa Fund accounts on the website. One is the TA account of Guangfa Fund Company, which starts with the number 27 and can buy most of the funds of Guangfa Fund. There is also an account starting with 98, and you can only buy small-cap funds of Guangfa. My Huaxia Fund also has two accounts, one starting with 03 and the other starting with 99F opened by Deng Zhong Company, so I can only subscribe for Huaxia Steady Growth Fund.

You don't need this account number to trade stocks and funds on the exchange. Just log in with your stock fund account number opened in the securities company and you can buy stocks.

I hope my answer is helpful to you.
