Why are there 50 air conditioners hanging on the wall of an apartment in Beijing?

The two "apartments" in Building 26, West Zone 3, Tiantongyuan, Changping District, are less than 100 meter apart. The houses are divided into small rooms of 6 to 15 square meters by partition or other means and rented out. Each rented house has a separate power distribution meter, water meter and air conditioner, and this is the scene where outdoor air conditioners are densely covered with a wall.

In this regard, the relevant person in charge of Tiantongyuan North Sub-district Office in Changping District said that once several "apartments" were found to be cut off, the original structure of the house was changed for rent, and the existing tenants stayed, which was a "group rent" chaos, and the joint property would be required, requiring the apartment to be dismantled and rectified within a time limit.
