Chan Tzi Ching was a famous Eagle Claw master. Known for his fighting, he never used more than three techniques to defeat an opponent. He developed his strength to such an extent that he could deliver full power in a three-inch punch.

Chan Tzi Ching was the first person to teach Eagle Claw in Southern China. In 1915, Fawk Yun Gap, a Mai Jong master in Ching Hoy Yun in the state of Tin Jun, invited Chan Tzi Ching to create the Ching Mo Gymnasium in Shanghai.
