First of all, what you need to confirm is whether you have bought funds and government bonds in CCB before. If so, is it your registered online banking account? If not, you need to go to the outlet to add the account to the online banking. Because there can only be one account for buying funds and government bonds. If you don't want to buy it with your previous account, you can also go to the bank and change it into your current card. And then buy and sell online.

If you haven't bought it before, you can try online banking first and have a look. After logging in to the Internet, click the "Investment and Financial Management" tab, which contains funds or foreign exchange business. For example, check the balance in the fund. If you are prompted that there is no fund transaction, you can buy and sell directly. If you are prompted that you need to sign a contract with CCB, you have to go again. Because in some places, opening an account will directly help you open a fund business, while in others, it will not. So I absolutely dare not come back to you.

I don't know. Are you satisfied with the answer?
