Ji Gong
According to legend, throughout the Jin, Yuan and Ming Dynasties few individuals had studied this art, one of them being "Ji Gong" (also known as Ji Longfeng and Ji Jike) of Shanxi Province. After Yue Fei's death, the art was 'lost' for half a millennium. Then, during the Ming and Qing Dynasties in Shaanxi Province's Zhongnan Mountains, Yue Fei's boxing manual was said to have been discovered by Ji Gong. It is more likely though that Ji Jike had created the art based on prior martial arts experience, or passed on an art that had already existed.
