The basic old-age insurance fund consists of employers, individual contributions and government subsidies.
Article 14
Personal accounts shall not be withdrawn in advance, and the bookkeeping interest rate shall not be lower than the bank time deposit interest rate, and interest tax shall be exempted. If an individual dies, the balance of the individual account can be inherited.
