Index funds adopt passive investment, choose an index as the imitation object, and buy all or part of the securities in the securities market included in the index according to the standard of the index in order to obtain the same income level as the index.

The biggest advantage of investment index funds lies in their low cost. In addition to saving money, index funds also have the advantage of protecting your investment from the influence of bad fund managers. You don't need to pay attention to the troubles of the fund like those who actively manage the fund, such as whether the investment team has changed or not, and whether the fund manager is still in office.

I suggest you choose a cross-market broad-base index (such as China A-share or Shanghai-Shenzhen 300), which is characterized by a relatively high market value coverage and can strive to obtain a relatively stable average market return. Generally speaking, even considering the disturbance of economic cycle, the long-term market will still grow with the economy.
