Hong Kong | ontheroofs : Due to the lack of the offers in the real estate market, Hong Kong housing is the most expensive in the world. It is 55% more expensive, than in London. Thereby, I’d like to tell you a story about the unique place named the Chungking Mansions. This rookery is located on the mainland (Kowloon). It is known for the cheapest flophouses in the city. In addition, it is a place where many immigrants (from India, Pakistan, Nepal, Bangladesh and so one) are hanging out.
