Get in the queue for public rental housing (公租房) if your housing is a problem

In plain words

You need to meet all three conditions: you have no home locally, or your living space is below the standard; your income and property are below the standard; and, if you are a migrant worker, you have held stable local employment for the required number of years. The waiting period is published locally. This is help for later and will not solve something urgent, but waiting in line costs nothing, and the earlier you sign up the sooner your turn comes.
