What is the difference between low-rent housing and public rental housing?

Low-rent housing and public rental housing are both housing security policies issued by the government, but they face different groups and rents. Low-rent housing is mainly for low-income families, and the rent is lower than the market price; Public rental housing is aimed at specific groups, and the rent is slightly higher than that of low-rent housing, but it can be obtained through rent allocation and market leasing. At the same time, the allocation standard of public rental housing is relatively high.
