Mr. Li Yulin (1888-1965), zirunru, a native of Anxin Circletou Village, Hebei Province. He lost his father at an early age and lived with his grandfather Li Shengtang. At the age of 7, he learned to learn literature and martial arts, and learned to form and yi fist under Hao Enguang as a teacher. Hao Enguang was a high foot of the "single knife" Li Cunyi, and Li Yulin's boxing skills were also instructed by Li Cunyi, and he accompanied Li Cunyi as a martial arts instructor in the Tianjin Chinese Warrior Association and Fulun Middle School. After Hao Enguang crossed to Japan in the east, Li Yulin was introduced by Li Cunyi and joined Sun Lutang. Because Li Yulin is good at kung fu and older, Tianjin Tongmen is often called a master brother.
Sun Lutang's second son, Sun Cunzhou, had an opinion on Li Yulin's personality and way of doing things, so that the contradictions between the two reached an irreconcilable level, and as a result, Li Yulin went to Shanghai.
In 1924, Li Yulin served as a martial arts instructor of the Chinese Sports Association and the president of the Shangde Samurai Association in Shanghai, during which time she was taught the Wudang sword technique by Li Jinglin. In 1930, Li Jinglin went north to establish the Shandong Guoshuguan, accompanied by Li Yulin, who served as the provost of the Guoshuguan. The Shandong GuoshuGuan opened a class to teach Yang-style Taijiquan, and Li Yulin invited Yang Chengfu's eldest disciple Wu Huichuan to come to the museum and helped finalize the eighty-one-style Yang-style Taijiquan. The eighty-one style became the original basis for the Yang-style national routine that Li Tianji later engaged in, and changed the real foot conversion to the virtual foot conversion. Li Yulin's Sun style of Taijiquan was learned from Sun Lutang, and the Yang style was obtained from Wuhuichuan, and it is also said that his Yang style was learned from Yang Chengfu when he was in Shanghai. Li Yulin and colleagues of the Guoshuguan edited a "Taijiquan Lecture Notes" as a lecture note in the museum, namely the Yang-style Taijiquan Eighty-One Style.
In 1936, Li Yulin established the Taijiquan Society (later renamed Harbin Taijiquan Research Society) in Harbin and introduced Taijiquan to the northeast. Located in Daowai South Badao Street, Taijiquan Mainly teaches Sun-style Taijiquan, Yang-style 81-style Taijiquan, Wudang Sword, Taiji Sword, followed by The Shape Meaning, Bagua and other boxing weapons.
With the increase in practitioners, the Tai Chi Chuan Society moved to a more spacious house on North Qidao Street and changed its name to "Tai Chi Research Society". The number of people who come here every day to practice is more than 200, including businessmen, clerks, students and other different classes. Li Yulin also established Taijiquan branches in Shenyang and Changchun. In the autumn of 1939, the second son, Li Tianji, came to Jilin to prepare for the establishment of the Beishan Taijiquan Research Society at the Beishan Guandi Temple. The following year, the "Beishan Taijiquan Research Society" was announced in the Beishan Fanxuetang to spread Taijiquan in Jilin City. Li Yulin's Taijiquan spread to all parts of the northeast centered on these four places, so that Taijiquan developed in the three northeastern provinces.
