It's actually quite simple. You go to their company and tell them that you have to hesitate to surrender (after the date of receipt of the policy plus 10 days). 10 yuan. They can't stop you, but don't back down. You just need to make up your mind. Then take out the China Insurance Regulatory Commission to scare the front desk. Did you sign all the signatures yourself? It is easier to have an agent signature, and the contract is directly invalid.
