The contract shall prevail! After signing the contract, you can read the terms of the contract carefully. If there is such a clause, don't worry. If there is no such clause, there will be a hesitation period of 10 days after the contract is obtained. If you surrender your insurance within this 10 day, only the fee of 10 yuan will be deducted, and the premium will be automatically returned to the deduction account. Or you can call Taikang Life Insurance Customer Service Center for telephone consultation, but there is no reliable first method!
