I suggest you don't buy any commercial insurance except accident insurance. It's all insurance under the nature of China, which is totally different from foreign countries. Foreign countries are based on protection, while China is based on money. Good accident insurance is very cheap, up to several hundred a year.
If it is dividend insurance, 99% of the current market is lower than the annual interest rate of banks. If it is universal insurance, you won't be much higher than the bank interest rate. It's better to deposit in a bank, which is convenient to access, and many banks will give you a large deposit and withdrawal discount, which is higher than universal insurance. If you use money to get it before it expires, you will definitely lose money, either at a loss or at interest, which is definitely lower than that of the bank. Another possibility is investment. There's no guarantee yet.
