Open Alipay and search for "pure debt", and some pure debt funds will appear in the system. When choosing, investors can choose according to the size of the fund, the target of fund investment and the fund manager. The specific method is as follows:

First of all, the size of the pure debt fund

The pure debt fund should choose a larger fund to invest, because the larger the fund, the better the effect of diversifying the risk of bond default, the lower the possibility of liquidation, and the larger the pure debt fund charges less.

Second, the past performance of fund managers.

Although past performance is history and cannot represent the future, history is the best way to understand the investment style of a fund manager. It is also the key to reflect the management level of fund managers. If a fund manager's past performance is lower than the Shanghai and Shenzhen 300 index all the year round, it means that management is conservative and cannot bring benefits to investors.

Third, look at the target of bond fund investment, the target bond is best above AA level.
