Here, I just want to summarize two features of the method.
1. Power comes directly from the feet and Dantien is just an important point in the energy transmission path. In other words, the source of explosive fajing is no longer the Dantien, but the feet.
2. The feet are constantly in a state of vibration. Traditionally, in Chinese martial arts, "toes grab the ground firmly," or "Yongquan contacts the ground closely."
You may read the article for more details or watch the following video clips about the founder of YiZungYue martial arts. These are excerpts from an interview with a TV station in Taipei. Someone in China (not associated with his group) posted the videos. The conversation is either in Chinese or Taiwanese.
