Yi Zong Bagua was founded by Master Zhang, Jun Feng in 1948 after closing his fruit wholesale business, "Han Gong Qiu", in Tianjin and moved to Taiwan due to the turbulence in China. He had changed his business to selling grains and flours instead and taught martial art at the old children's park by Jilong river in Yuanshan. Due to high demand and his own interest in martial art, along with difficulty in running his business, Zhang made teaching his career instead.

Zhang's Xingyi was a branch of the Hebei Li, Cun Yi system, his Bagua was from the Guanghua and Gao, Yi Sheng branch, and his Tai Chi was from the Hao style. Yi Zong is an amalgam of three styles and contains all three major internal styles. At the time there were no others in Taiwan teaching such a system, thus it was named Tai Shi Yi Zong (meaning First Yi Zong in Taiwan). The Yi Zong Martial Academy was founded in 1950 where Bagua, Xingyi and Tai Chi were taught.

While living in Tianjin, Zhang was a close friend of Wu, Meng Xia, often referring to each other as brothers. Wu introduced Zhang to Gao, Yi Sheng and had Gao teach Bagua pre-heaven and post-heaven palms at Zhang's home. Zhang also received guidance from Wu regarding internal hand methods and combat skills.

Gao, Yi Sheng
Gao Style Bagua
Gao, Yi Sheng, courtesy name De Yuan, (1866~1951), was born in Shandong Wuli county, Dashan village, Dazhuangzi (?).

Gao first learned Shaolin Da Hong Quan from his family and later learned Xingyi from a famous master, Li, Cun Yi. At the age of 30, he met Zhou, Yu Xiang at the Wafang village in Wuqing. Zhou was a skilled disciple of famed master Cheng, Ting Hua and renowned for his palm strikes, with a nick name of Jue Zhang (Terminating Palm).

After Gao was defeated by Zhou for three consecutive times, he asked to become a student of Zhou, but Zhou refused due to their close age. Instead Zhou brought Gao to Beijing and introduced him to Cheng (nicknamed Glasses Cheng). Cheng was the disciple of master Dong, Hai Chuan from Nancheng and trained with him for two years, acquiring the skill of eight palms. During the Boxer's Rebellion, Cheng was killed in a conflict with German soldiers. Gao was later introduced by Zhou to study Bagua under Master Yin, Fu and trained alongside Zhou for more than a decade. Subsequently, he traveled to and lived in the Zhou village in Shan Dong, near the Jiaoji railroad, teaching Bagua. There he met Master Song, Yi Ren from Guanghua, receiving knowledge regarding the 64 Post-heaven (entwining dissolving) palms and realizing that Bagua is only complete when both pre-heaven and post-heaven palms are acquired. Gao then returned to Tianjin and taught Bagua with both pre-heaven and Post-heaven 64 palms in a courtyard at the British Municipal Extension. After spending several decades of researching and fighting, he organized the many loose attack patterns and single drills of Cheng style Bagua to form his own unique training methods, creating the Gao style Bagua system. This system contains the circle walking pre-heaven palms and the straight stepping Post-heaven palms, with the pre-heaven palms constituting the prerequisite conditioning aspect of training and the Post-heaven palms training the applications.

Yi Zong Bagua was passed down from Master Zhang after his arrival in Taiwan in 1947. The classes were strict and famed for conditioning and combat. Every class was lead by Zhang and he demonstrated the techniques personally on his students. As such, many of his students had solid fighting skills and practicality and refinement of techniques are part of the tradition.

Teacher Luo, De Xiu learned Tan Shou Dao, Xingyi, and some Bagua techniques from Zhang's top student, Master Hong, Yi Xiang starting from 1968. After1974, he started focusing on Bagua and received many years of training under Master Hong, Yi Wen and Hong, Yi Mian (Master Hong, Yi Xiang's brothers). Teacher Luo has studied Yi Zong martial art for over 30 years, with students over Europe, United States and the Middle East.
