As for this book, Tang Hao looked through it in Chen Chunyuan's office in Chenjiagou and only copied the contents. At that time, Chen Chunyuan pressed "336 Boxing Manual", revealing only one page to Tang Hao. The word "six" in "336 Boxing" may have been blocked by Chen Chunyuan's finger and not seen by Tang Hao, or it may be because the pronunciation of the two sides was different at that time, or because Tang Hao was too emotional. There are two manuscripts of 336 Boxing Law, one written by Chen Xin and the other copied by Chen Chunyuan. Chen Xin's calligraphy spread to Chen Kezhong, and Chen Boxian read it in Chen Kezhong on 1963. Later, at the beginning of the Cultural Revolution, it rotted in Chen Kezhong's sweet potato cellar. Chen Chunyuan's copy was handed over to Chen Lixian, who later took it to Sichuan. In a war, Chen Lixian was afraid of living in an inhuman environment, so he tore up the copies page by page and set foot on the bamboo forest mud. So there is no original "336 Boxing Manual" in this world. Why is it called "336 Boxing Manual"? The first word "three" takes the dry "three", the dry triple is the yang is the sky, the last word "six" takes the Kun "three three", the Kun belongs to the yin and the ground, and the Chinese word "three" means three generations of "people": uncles and grandsons. It contains and becomes the image of heaven, earth, middle man and three talents. It means that three generations of grandparents and grandchildren have interpreted the theory of Taiji in heaven and earth, hence the name!
