First of all, the subscription fee or subscription fee may be different due to different purchase channels. So ask the rate of your trading channel fund first. Similarly, the redemption rate can also be queried.

Secondly, after knowing the rate, you can calculate:

Net subscription amount = subscription principal /( 1+ subscription rate)

Subscription fee = subscription principal-net subscription amount

Redemption fee = redemption share * redemption net value * redemption rate

The redemption rate can be reduced to 0.5% for long-term holding according to the holding time.
