Can I retire without a general social security account in Shanghai?

Of course. Retirement is mainly calculated according to the number of years and the amount of endowment insurance funds paid by individuals, so Shanghai household registration has no social security master account in Shanghai to apply for retirement. The reform of Shanghai's household registration policy clearly pointed out that "based on the new trend of the national household registration system reform, as well as the shortage of talents and the competition of talents in various places, the basic policy design framework of Shanghai's residence permit for registered population is put forward".
