Although different types of funds have different risk levels and income levels, buying one more fund is conducive to diversification of investment, but too many funds are inconvenient to manage and the risk control will be much weaker. If you want to diversify your investment, you can buy a fund portfolio, and you can also consider other investment and financial management methods, such as bonds, bank deposits, stocks and so on.
Investment and financial management are risky, and everyone should match financial products according to their own needs and risk tolerance.
