It is said that the stone lock originated from the military camps of the Tang Dynasty. Soldiers often used stone locks and stone burdens to exercise. Later, it spread among the people and evolved into a traditional competitive event that combines strength, skills, and fitness. This traditional folk fitness exercise uses sports equipment chiseled from stone to look like bronze locks for exercise. The methods include lifting, throwing, and catching. The lifting methods include single-handed push-ups and snatches; the throwing methods include flying throws, reverse throws, cross throws, and back throws; the catching methods include hand catches, finger catches, elbow catches, shoulder catches, and head catches, and can be combined into fancy training methods. The stone lock performance emphasizes height, floating, straight, stable, and active. The State Council announced the fifth batch of national intangible cultural heritage representative project lists and extended project lists. Taizhou Hailing stone locks were successfully selected into the extended list of national intangible cultural heritage representative projects.
