Can I buy a pair of social security when studying in Chengdu?

According to national laws and regulations, the same person is only allowed to have old-age security once in his life, but not twice. So as long as two places pay money at the same time, you must give up one.

Children studying in Chengdu and parents working in Chengdu can apply for admission with the labor contract signed with local enterprises in Chengdu, the certificate of working in this city, and the primary school (education department) near the working enterprise. After completing the formalities, you can enjoy the treatment of nine-year compulsory education in this city. (Free of tuition and fees)
