I don't understand the fund you are talking about. Bond grading funds are generally divided into Class A and Class B. For example, Boshi Yuxiang, Class A is the priority, Class B is the enterprising type, Class A has agreed income, and Class B has not agreed income. It can be understood that, just like ordinary shares and preferred shares in stocks, Class A fund shares are relatively less risky and less leveraged. Class B has high leverage ratio and high risk, and so on. Specific to what you said, because it is not a public open-end fund, you don't know how it is agreed. You should be careful about what the fund contract says and whether it is guaranteed. Personally, that's how it is understood. You study it again.
For example, Harvest Overseas.
