Contrary to popular belief, although the term Qigong (or Chi Kung) was used in all of the instances cited in the question, but it wasn't until 1953, when Liu Gui-zheng published a paper entitled "Practice On Qigong Therapy", that the term Qigong (Chi Kung) was adopted as the popular name for this type of exercise system. Prior to that date, there were many terms given to such exercise, such as Daoyin, Xingqi, Liandan, Xuangong, Jinggon, Dinggong, Xinggon, Neigong, Xiudao, Zhoshan, Neiyangong, Yangshengong, etc.
