The QDII fund share marked "RMB" refers to the subscription in RMB, and the redemption is also RMB; "USD cash/cash" means USD cash/cash is used for subscription, and USD cash/cash is also received upon redemption. The difference between RMB share and USD cash/cash income is mainly caused by exchange rate. Others, such as bond funds: generally, Class A income is higher than Class BC income. Although there is no subscription fee for the BC share, when calculating the net value of the fund every day, we should consider a sales service fee more than the A share, so the net income will underperform the A share.
