It is still necessary to buy critical illness insurance, because the incidence of serious illness is very high due to environmental pollution and food safety. When you get dozens of serious diseases (generally 3) covered by insurance clauses, you get high medical expenses.
Taikang Life Insurance is an old company, and its credit rating is fine. It must be reliable.
the quality of insurance depends on the specific terms, your personal financial ability, family and other conditions before you can judge, just like going to the mall to buy clothes, not everyone is suitable.
I hope it helps you.
