In 1886, Sun travelled around 11 provinces in China, in search of kung fu masters to test his skills. He visited Mountain Shaolin, Wudang, and Emei. No one met was able to win this young man. Sun return back to his hometown in 1888, founded a martial arts society by himself called "Pu Yang". In 1907, he was invited to the north-estern China.
    In 1912, Sun met a great Taiji master -- Hao Weizhen. At that time Hao was old and poor, living lonely in Beijing. Sun attended Hao in his illness, taking care of him like treating his own father. Hao was touched and taught all his Taiji techniques to Sun after his recovery. With a good foundation and sincere fondness of the art, Sun was miraculously quick to absorb Hao's decades of ideas and thoughts on Taiji Quan. Hao was astonished to find such a good disciple.
    It is in 1918 that Sun Lutang finally combiled the ideas of Xingyi, Bagua and Taiji together and founded the Sun Style Taiji. In the second year, Sun was invited to the President's Mansion and entitled an officer.
    During 1915-1925, Sun wrote five very important books -- Xingyi Quan Study, Bagua Quan Study, Taiji Quan Study, Quan Yi Shu Zhen (Genuine Narration of Quan and Its Meaning), and Bagua Sword Study which have profound influence to the following Chinese martial artists.
    In 1928, the most official administrative body of Chinese Kung Fu -- Nanjing Central National Arts Institution was founded, the already distinguished Sun Lutang was entitled as the Host of Wudang Men (administrating all Inner Kung Fu). He later withdrew from the institution because of some people's jealousness, and went to Jiangsu National Arts Institution to be its vice-president. He stayed in his position till 1932 when he returned to Beijing.
    In early Dec. 1933, Sun foretold his family that he was going to die soon. He was not ill at all but from the time he made his prediction, he stopped taking in food. His fast lasted for 20 days till one morning he ordered his family to take him in his chair to the courtyard, sat there sedately and after having said the last words "I look upon birth and death as only a game" Sun passed away quietly. Even his death was a great demonstration of the Tao of Taiji and the philosophy of the Oriental beings.
    Sun Lutang's successors include his daughter Sun Jianyun, his son Sun Cunzhou, and disciples such as Qi Gongbo, Sun Zhenchuan, Sun Zhendai, Jin Yunting, Chen Weiming, Qiu Deyuan, Li Yulin, Hu Fengshan, Ren Yanzhi, Chen Shouli, Zhu Guozhen, Zhi Xietang, Li Laodan, Cui Laoyu, Li Dunsu, Liu Rutong, Liu Zhongbang, and Zheng Huaixian. Among them, Sun Jianyun and Sun Cunzhou can be called the best.
