Kwai Tsing is one of the 18 districts of Hong Kong. It consists of two parts - Kwai Chung and Tsing Yi Island. Kwai Tsing is part of the New Territories. It had a population of 520,572 in 2016. The district has the third least educated residents and their income is below average.

Tsing Yi, sometimes referred to as Tsing Yi Island, is an island in the urban area of Hong Kong, to the northwest of Hong Kong Island and south of Tsuen Wan. With an area of 10.69 km2 (4.13 sq mi), the island has been extended drastically by reclamation along almost all its natural shore and the annexation of Nga Ying Chau (牙鷹洲) and Chau Tsai. Three major bays or harbours, Tsing Yi Lagoon, Mun Tsai Tong and Tsing Yi Bay (青衣灣) in the northeast, have been completely reclaimed for new towns.
