Cheng Man-Ching (1901-1975) was a renowned Chinese martial artist, physician, and calligrapher, known for his contributions to the practice and popularization of Tai Chi Chuan (Taijiquan) in the 20th century. He is often credited with helping to spread Tai Chi Chuan to a wider audience, both in China and internationally.

Cheng Man-Ching was born in China's Guangdong province and began his martial arts training at a young age. He studied various martial arts, but he became most famous for his practice and teaching of Yang-style Tai Chi Chuan, which is one of the most popular and widely practiced styles of Tai Chi.Cheng Man-Ching is perhaps best known for adapting the traditional long-form Tai Chi Chuan into a shorter, more accessible version known as the "Yang-style Short Form" or "Cheng Man-Ching's 37-Form," which consists of 37 postures.

This modification made Tai Chi Chuan more approachable for beginners and people of all ages, and it played a significant role in the popularization of Tai Chi as a health-promoting exercise.Cheng Man-Ching also emphasized the health and relaxation benefits of Tai Chi Chuan, and he often referred to it as a form of "moving meditation" that could improve physical and mental well-being.His teachings and his efforts to promote Tai Chi Chuan as a martial art, health practice, and cultural treasure had a lasting impact, and his students and disciples continue to pass on his teachings and legacy to this day. Cheng Man-Ching's contributions to the world of Tai Chi Chuan have left a lasting mark on the martial arts community and the broader field of mind-body practices.
