China Life Insurance Co., Ltd. was insured on April 5th. When do you pay the premium every year? Do you pay interest in September?

The grace period of insurance premium is 60 days. So it's 60 days now and your insurance policy has expired (that is, the insurance company will not pay for the insurance accident during this period).

You were insured on April 5, so the last payment date is June 4. It's already September, so you have to take the insurance contract, the applicant's ID card, the passbook, go to the company lobby to go through the reinstatement procedures, and interest.

You said you didn't charge interest last year, which is absolutely impossible.

Insurance companies will generally inform you whether your address and telephone number have changed. Instead of going to the insurance company to change it? Otherwise, the general insurance company will have a goodwill reminder.
