In the late Ming and early Qing dynasties, Dong Haichuan (played by Xie Miao) from Wen'an County, Hebei Province, learned martial arts from his uncle Dong Xianzhou. He was famous for his bravery in the village since he was a child. He loved to help the weak and act chivalrously. After he was a young man, he traveled to famous mountains and rivers, visited famous teachers and learned martial arts from masters. Later, in Jiuhua Mountain, he learned martial arts from the master Biyun Taoist. During this period, he fell in love with his junior sister Xuelian. After a series of joys and sorrows, Dong Haichuan never married for love. Dong Haichuan spent many years diligently comprehending "wearing Bagua and embracing Tai Chi", integrating the essence of martial arts in the world, and created the "Youshen Bagua Lianhuan Palm". After completing his martial arts, he went down the mountain and traveled outside the Great Wall. He defeated dozens of bandits alone and became famous outside the Great Wall. By chance, the person he rescued was the Fourth Prince who was visiting incognito, and the two became sworn brothers. He came to the capital alone to develop his career. He rescued the artist Jiang Long and the disguised Princess Ziyun when he saw injustice. Later, he stayed in the Fourth Prince's Mansion as a martial arts teacher to guard the palace. During this period, he competed with Prince Xiao and became famous in the capital. He was hired by Prince Xiao as the chief instructor of the guard. The original chief instructor Sha and his wife were dissatisfied and attacked Mr. Dong many times. Mr. Dong used his profound martial arts to escape danger and repayed his kindness with kindness and let him live. The most accomplished knights love their country and serve the people. In the end, Dong Haichuan defeated the Russian/French masters of the "World Kung Fu Group" in the Chinese and Foreign International Martial Arts Competition of the Eight-Nation Alliance, which promoted the country's prestige and inspired the national spirit. Emperor Xianfeng was very pleased and personally wrote the calligraphy of "Master of Bagua". Since then, Dong Haichuan has established a sect and has hundreds of disciples, becoming a generation of Bagua master!
