Fund conversion is to convert a fund held by an investor into a share of another fund. At present, fund conversion allows conversion between different types of funds, so this behavior is usually regarded as a special way for investors to redeem funds.

Under normal circumstances, if investors directly redeem the fund and then re-purchase a new fund, then at this time, they need to bear the redemption fee of the previous fund and the subscription fee of the latter fund. However, if it is in the form of fund conversion, it is only necessary to bear the redemption fee of the former fund and the subscription fee of the latter fund to make up the difference, so it is more cost-effective to convert the fund into green.
