Mom is 56 years old. I don't know what insurance to buy.

It is recommended to buy short-term accident insurance, because some long-term life insurance is not very "cost-effective" because of age. China Life Insurance, for example, has a special insurance program for the elderly, with a very wide coverage, which is very suitable for the elderly who are not flexible and prone to accidents. Other insurance companies have similar types of insurance with high cost performance. Another suggestion is to choose collective insurance, such as community or unit or village, which is more suitable and the rate is lower.
