Before 1999, the problem of paid use of welfare housing was widespread in government agencies, enterprises and institutions, so the "housing fund" was established. At that time, some units needed to use the housing fund for the maintenance of welfare housing distribution, so they could apply. However, it has basically disappeared for more than ten years, because welfare housing allocation has been cancelled for more than ten years. The previous welfare housing distribution has been confirmed to be owned by individuals, and who is responsible for maintenance has long been ignored by the unit. As for the housing provident fund center, in addition to managing the housing funds retained by various units more than ten years ago, its main function has been established as the housing provident fund management for the society. Housing provident fund is the personal property of employees (employees) paid in the unit, which has a statutory scope of use and cannot be applied for by the paying unit. Similarly, housing provident fund loans are for individuals and cannot be applied by the deposit unit.
