What room is the sparrow room?

"Ant Nest", "Capsule Apartment", "Dwelling House", "Pigeon Cage" and "Sparrow Room" ... In recent years, many headlines frequently appeared in newspapers actually refer to the same concept-the landlord transformed the original house into several partitioned rooms for rent. In some urban villages and ordinary residential areas in Wuhan, it is nothing new for owners to divide the original three-bedroom and two-bedroom into several small rooms and rent them to many people. The rent has gone up several times. A set of 100 square meter three-bedroom apartment can even be divided into ten "rooms in the room" for rent.
