Will social security automatically shift to first gear after entering the household?

After entering Shenzhen, social security will not be automatically transferred to Shenzhen. After entering the household, the employer needs to help modify the household registration information of medical insurance and change it to the household. According to Shenzhen's medical insurance policy, the level of medical insurance for employees in deep households is grade one, and non-deep households can choose one of grade one, grade two and grade three to participate in medical insurance.
