[[Cheng Man-ch'ing]] opened his school Shr Jung tai chi after he moved to New York from Taiwan in 1964. Unlike the older generation of practitioners, Cheng was cultured and educated in American ways,{{clarify|date=July 2017}} and thus was able to transcribe Yang's dictation into a written manuscript that became the de facto manual for Yang style. Cheng felt Yang's traditional 108-movement form was unnecessarily long and repetitive, which makes it difficult to learn.{{Citation needed|date=July 2017}} He thus created a shortened 37-movement version that he taught in his schools. Cheng's form became the dominant form in the eastern United States until other teachers immigrated in larger numbers in the 1990s. He taught until his death in 1975.<ref name="Lowenthal1991">{{Cite book |last=Wolfe Lowenthal |url=https://books.google.com/books?id=6ayJG1GU5Y4C |title=There Are No Secrets: Professor Cheng Man Ch'ing and His Tai Chi Chuan |publisher=North Atlantic Books |year=1991 |isbn=978-1-55643-112-8}}</ref>
