The front-end and back-end fund codes are different, such as: GF Jufeng, the front-end code is 270005, and the back-end code is 270015. If you have already committed to investing in the front end of a certain fund, you generally need to terminate the fund and then re-invest in the back end.

The online banking of the Bank of Communications is very convenient. I used the online banking of the Bank of Communications to make fixed investment. You can find the modified fixed investment fund in the fund supermarket and find the backend of the fund when selecting the fund (if the fund can be backed by the Bank of Communications) , it will be displayed), and other operations will be fine as required. However, although some funds have a back-end, you cannot choose the back-end at the bank. If so, you can go to the fund company's website to place your investment.
