Can a new car in Shenzhen be licensed to supplement social security?

You can't. According to the regulations of Shenzhen, when a newly purchased motor vehicle is licensed, it is necessary to provide a certificate that I or my close relatives have continuously paid 1 year social insurance in Shenzhen, and this certificate must be submitted when applying for a license. Therefore, if this condition is not met, you need to fill in the social security payment time before licensing. Shenzhen, referred to as Pengcheng for short, is a prefecture-level city, a sub-provincial city and a city under separate state planning under the jurisdiction of Guangdong Province.
