My children's grandmother bought an insurance policy in China Life Insurance. How can I check some information?

The place where the legal guardian signs is only used when the non-lineal relatives apply for insurance, that is, when the applicant is not the legal guardian, only one signature is used in this place, which is equivalent to the original authorization of minors to apply for insurance. If the applicant and the insured are immediate family members (parents, husband and wife, children), there is no need to sign there.
