There is no expiration date. The China Securities Regulatory Commission announced that currency funds do not have investment period issues because they are risk-free funds. Of course, the longer the holding period, the higher the returns. It can be said that the longer the bond fund is, the better. After all, it is low risk. It holds about 80% of the bonds. No. 01215 has now announced the "Regulations on Matters Concerning the Investment of Securities Investment Funds by Fund Practitioners", which will be effective from the date of announcement.
