As for Tai Chi Chuan, it is different from the above. The above is aimed at the internal organs and meridians of the human body. Tai Ji Chuan is a complete movement. Through the overall slow exercise, the slower the exercise, the faster the qi and blood, so the exercise of health care must be slow. Wudang Taiji Chuan and Zhang Sanfeng You 17 School evolved from Zhang Sanfeng School. At the end of the Ming Dynasty, the situation was turbulent, Taoist priests were scattered among the people, and many methods were circulated among the people. The Biography of Chen Tai Ji originated from Zhao Bao, Zhao Bao originated from Zhang Sanfeng and Liu Chuan originated from Wang Zongyue. Chen Dali's stamp-stamping style is far from the gentle style of all factions. More appropriately, Chen-style cannon hammer or Taoist two-instrument boxing will only feel uncomfortable if you don't practice Taoist inner alchemy for a long time. Yang Luchan, his son and grandson, and their direct descendants all respect Zhang Sanfeng as the founder. When Zhang Sanfeng gathered more than 400 people to preach Tai Chi, there was a saying, "May the heroes in the world live a long life, not at the end of the attack." Therefore, practicing the gentle Tai Chi Chuan is the Tai Chi Chuan of keeping in good health. If you are quick at martial arts, you will hurt Neidan. It's okay to practice young. After practicing for decades, I consider the wear and tear of joints myself.
