The choice of critical illness insurance gives priority to powerful companies, which have strong solvency, fast claims and secure future. Secondly, the cost performance of products must be high, and diseases should be relatively rich. Accidental death and high disability should also be included.
I recommend Corning Lifetime and Credit Suisse of China Life Insurance. The former is pure guarantee and lifelong guarantee. It is the first health insurance in China, with the highest market share and the highest cost performance, which is about 5% cheaper than similar products on the market. The latter pays dividends every three years. Moreover, dividends and returns can be converted into sickness insurance, which is more flexible. At the age of 80, the return is three times the basic insurance amount.
