Is it still a point to buy a house in Shanghai and seal up social security households?

Not exactly. Stamping the house purchase account refers to the interruption of payment (transfer out but not transfer in), and the interruption of Shanghai social security refers to the fact that the social security households who seal the house purchase do not count as points. According to the "Detailed Rules for the Implementation of the Measures for the Administration of Shanghai Residence Permit Points", those who hold the "Shanghai Residence Permit" can apply for residence permit points if they have legally and stably lived, legally and stably employed in this city and participated in social insurance for employees in this city for six months. When applying for Shanghai residence permit points, Shanghai residence permit holders should be in the state of employment and payment of social insurance for employees in this city in the month of application, and have paid social insurance for employees in this city for 6 months (excluding supplementary payment) in the previous 12 months, they can apply for Shanghai residence permit points.
