To tell the truth, the annual income difference of the money fund is particularly small. For example, in 2009, the difference between the highest returns and the lowest returns of all money funds was only a little more than 1%, and the annual returns fluctuated slightly, so I suggest you close your eyes and choose one, as long as you are not particularly unlucky, it is enough to achieve a medium return. In addition, the money fund is designed to effectively resist inflation and has strong liquidity, but it is not suitable for you to do all funds. You can make some long-term investments such as fixed investment appropriately, and the income may be more objective. I hope it helps you, and I wish you a happy financial management ~
