Why is there an empty account in the personal account of the endowment insurance fund? Please be more specific. I got my homework. Thank you.

1993 The Third Plenary Session of the 14th CPC Central Committee adopted the Decision of the Central Committee of the Communist Party of China on Several Issues Concerning the Establishment of a Socialist Market Economic System, which pointed out that "the pension and medical insurance for urban workers shall be shared by units and individuals, and social pooling shall be combined with individual accounts". 1995, the State Council issued the notice on deepening the reform of the old-age insurance system for enterprise employees (Guo Fa [1995] No.6), which further established the fund accumulation system of basic old-age insurance. 1997, the State Council issued the "Decision on Establishing a Unified Basic Old-age Insurance System for Enterprise Employees" (Guo Fa [1997] No.26), which further clarified the system mode of combining social pooling with individual accounts for basic old-age insurance. According to the instructions of the CPC Central Committee and the State Council, a personal account system of basic old-age insurance based on individual contributions has been established in various places. In the actual implementation, due to the failure to fully compensate the renovation cost in time and other reasons, the personal account fund that should have been accumulated is paid in the current period, which leads to the phenomenon of "empty account" in the personal account of the basic old-age insurance, and the original intention of the basic old-age insurance system with partial accumulation system has not been realized. In order to prevent the risk of providing for the aged brought by the peak of aging, the State Council clearly requires in the "Pilot Program on Improving the Urban Social Security System" (Guo Fa [2000] No.42) that "social pooling funds and individual account funds shall be managed separately, and social pooling funds shall not occupy individual account funds."
