In September 2011, a "container dormitory" with an internal space size appeared on a construction site in Zhengzhou. It is reported that there are more than 600 dormitory rooms in Zhengzhou, while there are thousands in the whole province.
Container dormitory is a habitable dormitory made of containers after a certain transformation. Most of these residents are relatively poor migrant workers. Such cheap and easy-to-relocate dormitory is very popular.
But until now, the container develops very quickly. And it already is exported to some African country as family living, as office.
