How does Hong Kong protect the housing of the poor?

I am not an expert in this field, and I dare not judge the current affordable housing policy, but I have lived in Hong Kong for many years and want to talk about it here. In Hong Kong, the government will first make a thorough investigation of the whole city, select several places that are estimated to be impossible to develop in five years by relying on the market mechanism, and turn them into low-rent housing development zones. The government allocates land free of charge, invites developers to build houses according to the principle of economic application, and the government buys and rents them to the poor. Low-rent housing rent 1/3 or lower than that of commercial housing. According to the policy, low-rent housing tenants have the right to spend money to buy low-rent housing as their own property after living in low-rent housing for five years. Since it is their own property, of course, they can buy and sell it freely, so five years ago, many poor people quickly stepped onto the life steps of having a house to live in and a house to sell through the support of low-rent housing policy. While developing low-rent housing, the Hong Kong government has also invested a lot of money in road construction in this area to ensure that buses extend in all directions and facilitate the poor to "eat" in downtown areas. The government will also issue a five-year development plan for the region, so that the poor can see hope and business opportunities. Therefore, people who apply for low-rent housing flock. The next step is to strictly examine the qualifications and queue up. This step first makes the rich who are trying to be opportunistic not to join this kind of "excitement". Citizens applying for low-rent housing fill in the application form issued by the government and queue up on the computer. They don't need to find a relationship for help, just wait for the notice. You can't choose the location of low-rent housing. Not according to the designated place to enjoy low-cost housing treatment, disqualification. If you still want to apply, queue up again. Poverty is always a problem. The next step is to punish severely. Some mainland immigrants have houses in the mainland and applied for low-rent housing in Hong Kong. After a few years, they were found out by the Hong Kong government and disqualified. This is a waste of time. A lawyer in Hong Kong filled out a form with false information. After several years, he bought a low-rent house and was found to be unqualified. As a result, he went to prison. There are many poor people everywhere who need government care. If there are many poor people, society will not develop. This truth is understood by any government. In fact, it is normal for Kunming's affordable housing sales to be cold, and the real poor can't afford to buy a house. This is the essence of the problem. How to solve the housing problem of the poor reflects the management level of the government. The author thinks that the low-rent housing policy in Hong Kong can be used for reference. Another reason is that the government must provide land and real money to help the poor, and the idea that "wool comes from sheep" will not work.
