Wing Chun (Chinese: 詠春; pinyin: yǒng chūn; literally "spring chant"), also romanised as Ving Tsun or Wing Tsun, (and sometimes substituted with the characters 永春 "eternal springtime"); (also known as Snake-Crane style); is a concept-based Chinese martial art and form of self-defense utilising both striking and grappling while specialising in close-range combat.

The alternative characters 永春 "eternal spring" are also associated with some other southern Chinese martial arts, including Weng Chun Kungfu and White Crane Weng Chun (Yong Chun).

The earliest known mentions of Wing Chun date to the period of Red Boat Opera.

The common legend as told by Ip Man involves the young woman Yim Wing-chun, (Wing Chun literally means 'forever springtime' or 'praising spring',) at the time after the destruction of the Southern Shaolin Temple and its associated temples by the Qing government:

After Wing-Chun rebuffs the local warlord's marriage offer, she says she'll reconsider his proposal if he can beat her in a martial art match. She soon crosses paths with a Buddhist nun--Ng Mui, who was one of the Shaolin Sect survivors, and asks the nun to teach her boxing. The legend goes that Ng Mui taught Yim Wing-Chun a new system of martial art that had been inspired by Ng Mui's observations of a confrontation between a Snake and a Crane; this then-still nameless style enabled Yim Wing Chun to beat the warlord in a one-on-one fight. Yim Wing-Chun there-after marries Leung Bac-Chou and teaches him the style, which is later named after her.

A wing is an appendage with a surface that produces lift for flight or propulsion through the atmosphere, or through another gaseous or liquid fluid. A wing is an airfoil, which has a streamlined cross-sectional shape producing a useful lift to drag ratio.

The word "wing" from the Old Norse vængr for many centuries referred mainly to the foremost limbs of birds (in addition to the architectural aisle.) But in recent centuries the word's meaning has extended to include lift producing appendages of insects, bats, pterosaurs, boomerangs, some sail boats and aircraft.

"Wing" can also mean an inverted airfoil on a race car that generates a downward force to increase traction.

Various species of penguins and other flighted or flightless water birds such as auks, cormorants, guillemots, shearwaters, eider and scoter ducks and diving petrels are avid swimmers, and use their wings to propel through water.

A wing's aerodynamic quality is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.

Jackie Chan, SBS, MBE (born Chan Kong-sang, 陳港生; 7 April 1954) is a Hong Kong-born Chinesestuntman, actor, and director whose perilous acrobatic stunts and engaging physical humour made him an action-film star in Asia and helped to bring kung fu movies into the mainstream of American cinema. In his movies, he is known for his acrobatic fighting style, comic timing, use of improvised weapons, and innovative stunts. Jackie Chan has been acting since the 1960s and has appeared in over 100 films.

Chan has received stars on the Hong Kong Avenue of Stars and the Hollywood Walk of Fame. As a cultural icon, Chan has been referenced in various pop songs, cartoons, and video games. An operatically trained vocalist, Chan is also a Cantopop and Mandopop star, having released a number of albums and sung many of the theme songs for the films in which he has starred. In addition to acting, Chan pursued a career in the Hong Kong music industry, releasing a number of original albums beginning in 1984. He founded the Jackie Chan Charitable Organization in 1998, which, among other projects, offers scholarships to Hong Kong youths, and he worked as a goodwill ambassador for UNICEF.

Chan Wah-shun (陳華順) (c. 1836–1909), nicknamed 'Money Changer Wah' (找錢華), was a student of the wing chun grandmaster Leung Jan (梁贊). He is best known today for being the martial arts teacher of Yip Man, himself best known for being the teacher of Bruce Lee.

Chan owned a coin changing stall near Leung's herbal medicine clinic in Foshan. He carried heavy loads of coins every day, and so developed great strength over the years. Chan had learned martial arts from others before learning wing chun.^{[citation needed]} Leung had only a few private students at the time, including his sons Leung Chun (梁春 loeng4 cheun1) and Leung Bik (梁壁 Liáng Bì; loeng4 bik1), another student Woodman Wah (木人華), and Chan.

The Qing government recruited Chan to be the head instructor of the army, but he served in that position only temporarily before returning home. Chan also learned traditional Chinese Medicine (de da, 跌打) from Leung, eventually closing his money changing business and opening a healing clinic. Chan accepted his last student, Yip Man, when he was 70 years old, but was only able to teach him for three years. Before dying, he asked his second student, Ng Chung-sok, to continue Yip's training after his death.

Doctor Kevin Chan is currently an emergency physician at the Hospital for Sick Children, Toronto.

He received a Bachelor of Science B.Sc. (Hon.) from the University of Toronto, an MD from the University of Ottawa, and an MPH From Harvard University. Currently completing work for his DPH at Harvard.

In 1994, Dr. Chan co-founded the Student University Network for Social and International Health or Reseau Etudiants Universitaire Pour la Sociale et Sante Internationale. He also helped found the Centre for International Health and Development at the University of Ottawa and the Centre for International Health at the University of British Columbia.

In 2001-2002, he was co-chair of the Canadian Society for International Health, and between 2001-2003 he was President of the International Child Health Section of the Canadian Paediatric Society. He was the recipient of the Chris Krogh award Prize from the Global Health Education Consortium.

He is the winner of the Frank Knox Memorial Fellowship from Harvard University in 2002. In 2003, he won the Johnson & Johnson Physician Scholarship in International Health. Currently, he holds the Pierre Elliott Trudeau Foundation Scholarship from Canada.
