If you plan to hold the fund for one or two or even three or five years, you can buy a regular open debt base, called fixed debt, in addition to the ordinary long-term pure debt base. The closed operation period of fixed-term open funds is at least half a year and at most three years, during which investors may not apply for redemption. In the meantime, fund managers don't have to consider the pressure of redemption and try their best to invest. After the closure period, there will be an opening period of at least two or three days and at most one month for investors to purchase and redeem. This mechanism makes it easier to obtain high returns by regularly opening the debt base than by ordinary debt base.

There are three points to pay attention to in screening excellent term bonds.

First, we should choose to open the pure debt fund in the debt base regularly, and don't touch stocks.

Second, don't choose debt bases with excessive leverage, that is, funds that require banks to borrow a lot to buy bonds. The suggested maximum amount should not exceed 160%.

Third, half a year is a bit short, and two or three years is a bit long. It is recommended to choose a regular open debt base with a closed period of one year, and then buy it after the next opening time.
