Professor Leung Ting () is the founder and president of the International WingTsun Association. The worldwide proliferation of WingTsun KungFu is largely due to the efforts of Professor Leung.

Leung Ting began learning Wing Chun kungfu at the age of 13 from Great Grandmaster Yip Man's first student in Hong Kong. In 1967, Leung Ting began teaching WingTsun Kungfu as an amateur instructor. In 1968, he started a WingTsun class at the Baptist University, becoming the first kungfu class ever established at a university in Hong Kong. Earlier that year, Great Grandmaster Yip Man (teacher of Bruce Lee) had just "closed his door" — a Chinese phrase that means to retire from teaching. However, he soon accepted Leung Ting as his "closed-door" student and personally taught him the most advanced techniques in the home of Leung Ting's Second Si-Hing (elder kungfu brother), Kwok Keung.

Soon, a young Sifu Leung Ting realized that what he was learning from the Great Grandmaster was quite different and far more profound than what he had previously learned. He started to appreciate the most advanced ideas of "unloading the force from the strong opponent and defeat him by making use of his own force". To distinguish his newfound understanding of the art, he chose to spell in English his interpretation of the style as "WingTsun," which, although pronounced the same, is quite different in concept from the generic spelling of wing chun. However, the most important point is not the difference in spelling; it is the difference between the "superficial techniques that look alike" and the "profound fighting concepts behind these techniques"!

The Leung Ting Gym and IWTA Headquarters is located in the very location where Great Grandmaster Yip Man last taught publicly. After deciding to fully retire from teaching, he appointed Grandmaster Leung Ting to take over his class. To this day WingTsun is still taught in this space on Nathan Road in Kowloon, Hong Kong.
