Talking about Chinese Internal Arts often results in misspellings and unnecessary misconception.
An attempt at clarity:
太極拳
Tai Chi – Taiji – Taijiquan - T’ai Chi Chuan
Correct full name of the internal martial art: Taijiquan (pronounced: taj dzji tsjwen)
Correct name for the symbol : Taiji
T’ai Chi Chuan and Tai Chi are old spelling, using the obsolete Wade-Giles system to transpose Chinese sounds to our alphabet. Today we use PinYin, combined with tone indication: tai4 ji2 quan2
氣功
Chi Kung - Qigong – Daoyin
Correct modern name for health exercises: Qigong (qi4 gong1)
Ancient correct name for health exercises: Daoyin ?? (dao3 yin3)
Chi Kung is old spelling (Wade-Giles).
