The principle of "amount subscription and share redemption": that is, the subscription is applied according to the amount and the redemption is applied according to the share;

"First-in, first-out" principle: When the fund share holders redeem, the fund manager will handle the fund share of the holder's account in the sales organization according to the principle of first-in and first-out, that is, the confirmed share will be redeemed first, and then the confirmed share will be redeemed to determine the applicable redemption rate.
