<Li> Sun style (孫 氏) of Sun Lu - t'ang (1861--1932) </Li> <P> The order of verifiable age is as listed above . The order of popularity (in terms of number of practitioners) is Yang, Wu, Chen, Sun and Wu / Hao . The major family styles share much underlying theory, but differ in their approaches to training . </P> <P> There are now dozens of new styles, hybrid styles, and offshoots of the main styles, but the five family schools are the groups recognized by the international community as being the orthodox styles . Other important styles are Zhaobao tàijíquán, a close cousin of Chen style, which has been newly recognized by Western practitioners as a distinct style, the Fu style, created by Fu Chen Sung, which evolved from Chen, Sun and Yang styles, and also incorporates movements from Baguazhang (Pa Kua Chang) and the Cheng Man - ch'ing style which is a simplification of the traditional Yang style . </P> <P> Most existing styles can be traced back to the Chen style, which had been passed down as a family secret for generations . The Chen family chronicles record Chen Wangting, of the family's 9th generation, as the inventor of what is known today as tàijíquán . Yang Luchan became the first person outside the family to learn tàijíquán . His success in fighting earned him the nickname Yang Wudi, which means "Unbeatable Yang", and his fame and efforts in teaching greatly contributed to the subsequent spreading of tàijíquán knowledge . The designation internal or neijia martial arts is also used to broadly distinguish what are known as the external or waijia styles based on the Shaolinquan styles, although that distinction is sometimes disputed by modern schools . In this broad sense, all styles of t'ai chi, as well as related arts such as Baguazhang and Xingyiquan, are, therefore, considered to be "soft" or "internal" martial arts . </P>
