Take Haifutong Steady Profit-adding Bond Fund as an example. At first, there was only one C-type model, and no subscription fee was charged. After holding it for 3 days, no redemption fee was charged, but the sales service fee was paid daily. After that, a new category A charging method was added, which charged subscription fee and redemption fee, but did not charge sales service fee. Of course, in the class A charging mode, there is no redemption fee after holding it for 3 days.

a: the new charging mode is added to meet the different financial needs of investors. Class A charging model, as long as investors hold it for more than 3 days, only needs to spend the subscription fee, which is suitable for those investors who have invested for a long time and can meet their liquidity needs. As for the C-type charging mode, since the sales service fee is paid on a daily basis, it is more appropriate to choose this mode if investors have high liquidity requirements for funds and the investment period is relatively short.
