The housing assistance system is a housing security system provided by the state to public rental housing, low-rent housing, affordable housing, etc. for households without housing in financial difficulties. In other words, if a certain rent is given, they will have a house to live in.

The housing provident fund system is that the state provides certain housing subsidies to working employees, which are deposited into individual accounts through personal contributions and government subsidies, and can be withdrawn or provided fund loans when the time comes to purchase a house.
