Zhang Sanfeng
Zhang Sanfeng is purported as having created the concept of "neijia" () in Chinese martial arts, specifically "taijiquan", a Neo-Confucian syncretism of Shaolin martial arts with his mastery of "daoyin" (or "neigong") principles. On one occasion, he observed a bird attacking a snake and was greatly inspired by the snake's defensive tactics. It remained still and alert in the face of the bird's onslaught until it made a lunge and fatally bit its attacker. This incident inspired him to create a set of 72 "taijiquan" movements. He is also associated with the Taoist monasteries in the Wudang Mountains.
