Kwai Tsing (Chinese: 葵青區; Cantonese IPA: kʰwɐi¹¹ tsɪŋ⁵⁵ kʰɵy⁵⁵; Putonghua Pinyin: Kuíqīng Qū) 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 477,092 in 2001. The district has the third least educated residents and their income is below average.

Kwai Tsing did not exist as a standalone district when Hong Kong's District Boards were formed in the early 1980s. It remained as a part of Tsuen Wan district until 1985. The newly created district was known as Kwai Chung and Tsing Yi District (葵涌及青衣區) until 1988, when its name was shortened to Kwai Tsing District.

The internationally famous container terminals can be found within the district, along the shores of Rambler Channel between Kwai Chung and Tsing Yi Island. The Tsing Ma Bridge, leading to the Hong Kong International Airport through the North Lantau Highway, starts at the northwestern end of Tsing Yi Island.

Over 75% of the district residents live in public housing.

The Kwai are an insectoid humanoid fictional species in the DC Comics universe, created by Dan Abnett, Andy Lanning and Oliver Coipel. Allies of the Legion of Super-Heroes, they were a nomadic, matriarchical people who mostly displayed a pacifistic approach to life. The few exceptions to the last of these, such as Shikari, were dubbed "Lonestars".

The Kwai are one of the thousands of species Element Lad was ultimately responsible for the creation of after he became stranded a billion years in the past of the "Second Galaxy," in his indefinitely prolonged lifespan. They were an insect-like humanoid race, whose distinguishing features included slate-grey skin with black tattoo-like markings, dragonfly-like wings, retractable armoured exoskeletons and the ability to find any path if such existed, even without obvious tracks to follow.

Their travels usually led them to follow "feral stars" - newly appearing stars in their path - which they considered good luck. When, in the 31st century, Element Lad's home time period, they followed a "star" which was in reality the Legionnaire Wildfire, it led them to encounter the Progeny, a xenophobic beetle-like race who began to hunt them down. While fleeing from a Progeny attack which killed two of her friends, Shikari would encounter the other Legionnaires, held in stasis, who had been flung through a rift to the Second Galaxy - though displaced only in space rather than time and space. Revived, they aided her in driving off the Progeny, then followed her to their "brief-home," where they helped the Kwai to gather resources for moving on, and the Kwai helped in turn to make their heavily damaged ship functional, and created a new containment suit for Wildfire from their plastic-like "Use-weave". They and the Legion then went their separate ways, although Shikari would remain with the team.

Wong Tai Sin or Huang Da Xian is a Chinese deity popular in Jinhua and Hong Kong with the power of healing. His name literally translates to the "Great Immortal Wong (Huang)". Wong Tai Sin is purportedly the divine form of the individual "Wong Cho Ping".

According to the Self-Description of Chisongzi (Master Red Pine) (赤松子自述) that is kept at the Wong Tai Sin Temple in Hong Kong, Wong Tai Sin was born under the name Wong Cho Ping (黃初平, Huang Chuping in Mandarin Chinese) in 338 in today's Lanxi, Jinhua, Zhejiang Province. Western sources have him listed at (c. 284-364 CE).

Wong Cho Ping is said to have experienced poverty and hunger and to have become a shepherd when he was eight years old. He began practicing Taoism at the age of fifteen after meeting a so-called 'immortal' or saintly person in the Red Pine mountain in his hometown. Forty years later, he was said to have been able to transform stones into sheep. He is also known as the Red Pine Immortal (赤松仙子), named after his hermit mountain. His birthday is purported to fall on August 22 of the lunar calendar.
