The Heaven Sword and Dragon Saber is a classic costume sword-play drama. With the growth of the main character Zhang Wuji, the story tells about the heroes of Wulin (the martial-arts circle) and their resistance against Mongolian aristocratic at the end of the Yuan Dynasty (about 1368 AD). There have been clues to Chinese traditional culture in the drama, such as Tai Chi and Traditional Chinese medicine. The stories of Zhang Wuji saving many people with Chinese medicine and treatments embody the core spirit of traditional Chinese medicine—helping the world and protecting life with benevolence and goodness.
