Unlike his brother Xing Qiao's art that was significantly influenced by Liuhebafa's Weituo Gong and other arts - Han Xing Yuan's expression of Yiquan retained the flavor of his extensive training in Xingyiquan. Famous for fighting, Han Xing Yuan was an enforcer for a triad organization in Shanghai until he was severely beaten and left for dead. Rescued by Christian missionaries and sent to Hong Kong for medical care, Xing Yuan converted to Christianity later in life. While not known to be a particularly kind person, the younger Han was quite martially effective.

Henry Look primarily learned Guang Ping Yang Taijiquan from Kuo Lien-Ying, starting in 1968. From Kuo he also learned the 5 Element Fists of Xingyi and Universal Embracing Post from Yiquan. Grandmaster Look pursued other instructors, most likely due to Kuo's alcoholism. Han Xing Yuan came to the United States in the 1970s and Henry Look was first introduced to him then. Other famous instructors who trained with Han at that time include Fong Ha who also did Dong Family Taijiquan and Sam Tam who was known for his Eagle Claw and Taijiquan as well.

As an architect for Benihana, Look would regularly travel to Japan on business. During those trips he made a point to visit Han Xing Yuan in Hong Kong as he was nearby and could fly there more easily than from San Francisco directly. Yu Pengxi was brought to the United States in 1981 or shortly thereafter by Martin Lee and Grandmaster Look began to train with him. From Yu he learned some Baguazhang, Xingyiquan, and Yiquan Fajin in addition to the Vajrayana material that Yu offered for empty force. In 1984 all three of Grandmaster's teachers passed away. Shortly after the passing of his previous instructors, he visited Han Xing Qiao for a week long period of clarification and received some instruction from him. Grandmaster continued to train with Yu's wife Min Ouyang after he passed. 

My Han Family Yiquan teacher is Nick Domich, one of Henry Look's junior students who moved on to Han Xing Qiao's system through Martin Wong for almost a decade until Martin's passing. Martin trained with Han Jing Chen, Henry Look, and Sam Tam, reinforcing the influence of the Han family. I have learned some of the Qigong aspects of Grandmaster Look's Yiquan from Dug Corpolongo who was his fifth disciple. Nick and I exchanged Baguazhang and Yiquan in a one on one format - he considers himself more of a coach than a traditional Sifu. Additionally, I have done private training with Ray Carbullido for the arm swings and how to integrate it with Baguazhang.
