Opening online banking and fund business is not a bonus. It means that CCB has handled the fund business for you without telling you. That is to say, from now on, the bank will deduct a fixed sum of money from you every month to buy the fund you designated. You should have a fund on your list. To put it bluntly, it means that the basic people (such as you now) entrust money to fund companies for investment, such as stock trading and buying bonds. Everyone shares the gains and losses. The advantage of fixed investment is long-term investment, which relatively disperses risks, which is equivalent to zero deposit and lump sum withdrawal, just buying it in the fund. If the bank doesn't make it clear to you, such as risk warning, it's really not authentic.

It's easy to cancel the contract. Just go to the counter and apply for cancellation.
