Info about "Chuojiao video"
Chuojiao (poking foot) is a Chinese martial art that comprises many jumps, kicks, and fast fist sequences. The fist and feet work in unison and strike continuously forward, like “falling meteorites”, never giving the opponent a moment to recover. The qing gong portion of this style’s training involves a practitioner jumping against a wall with heavy weights affixed to his/her calves. This style is practiced mainly in central Hebei, northern China, Beijing and Liaoning in North-eastern China.
