The state strictly monitors the investment channels of insurance companies. Insurance companies cannot participate in high-risk investment projects. Suppose you lose money all the year round or earn less, then you get less dividends. The general dividend insurance has a fixed return, which is called the blessing part. No matter whether the insurance company is profitable or losing money, there will be no shortage of blessings.
Moreover, insurance companies have reserves in the central bank, and insurance companies will use these reserves when they have financial problems.
As for 70% of the profits, the CIRC will supervise and audit them. Including complaints against insurance companies, you can also go to the China Insurance Regulatory Commission to complain.
