The front end collects subscription fees at the time of purchase, and the back end collects subscription fees at the time of redemption.

Details are as follows.

If there is a back-end charge, it is best to hold the back-end for a long time. The longer the time, the less the subscription fee.

If the fund has a redemption fee, no matter the front-end or back-end charging mode, the redemption fee will be charged at the time of redemption. However, some funds also set redemption fees according to time. If it reaches a certain holding time, the redemption fee may be zero.
