At the age of 55, I bought Taikang Healthy Life C Pension Security and Taikang Additional Healthy Life C Critical Illness Insurance. Is it suitable?

First of all, insurance is not appropriate. The one you bought is ok, that is, it only covers 30 diseases, but enjoying well-being is different. 45 kinds, if guaranteed. Although it is guaranteed to be 80 years old, 128% can be retired at that time, which is not bad.
