Bond funds are divided into three categories: pre-A fees, post-B fees and C service fees. The only difference between Class A and Class C bond funds is the different charging methods, and there is no difference between management fees and custody fees.

The difference between the two charges: Class C mode does not charge subscription fee, and does not charge redemption fee after holding for 30 days, but draws sales service fee on a daily basis. Mode A charges the subscription fee and redemption fee, but does not charge the sales service fee. A mode charging mode is held for 30 days, and no redemption fee is charged.
