Chungking Mansions is a famous building in Hong Kong, China. It is located at 36-44 Nathan Road in Tsim Sha Tsui. The building features a labyrinth of guesthouses, curry restaurants, African bistros, clothing shops, sari stores, and foreign exchange offices. It often acts as a large gathering place for some of the ethnic minorities in Hong Kong, particularly Indians, Middle Eastern people, Nepalese, Sri Lankans, Bangladeshis, Nigerians, Europeans, Americans, Pakistanis, and many other peoples of the world. The building was completed in 1961, at which time Chinese residents predominated. Now, after more than four decades of use, there are nearly 4,000 people living in the Mansions.
It is also known to be a centre of drugs, and a refuge for petty criminals, scammers, and illegal immigrants. The strange atmosphere of this building is sometimes called by some "the scent of Kowloon's Walled City".
The Chungking Mansions served as one of the filming locations for Wong Kar-Wai's movie, "Chungking Express".
