the official name of the house card house is "Suzhou urban public housing" (not involving public housing in other areas), and the official definition is: residential housing managed by the real estate management department with rent standards set by the government.

Before the 1981s and 1991s, many houses in China were issued by "units", and the units also issued a "room card" to everyone, so it was commonly known as "room card room". Housing card housing actually refers to the state-owned real estate managed by real estate management departments at all levels in the country, including the welfare housing built by state-owned and large collective enterprises and institutions in the planned economy era.

in fact, the house card room is what we usually call public housing, and we can live at a very low rent. Due to the long history of construction, the living environment of most card houses is very general or even bad.

Most of them are bungalows located in alleys. Most cars can't get in. Some of them don't even have bathrooms and kitchens, so they have to go to the public security and build stoves in corridors or yards.

But the room card room has three advantages: school district+small area+low total price, so it is loved by a large part of people. And some room card rooms correspond to the top primary or secondary schools, which makes the room card room become popular.

However, Suzhou's room card houses should be mainly concentrated in gusu district, and they can only be purchased with gusu district hukou and other conditions. In addition to self-occupation, many of them are used to operate as homestays.
