The Sun-style long form that Sun Lutang describes, move by move, in his book, Taijiquan, consists of 98 movements and echoes the overall structure of both the Chen and Yang long forms. It’s quite a bit shorter, however; it only takes about seven and a half minutes.
Here is a video of the Sun 98, with names, demonstrated first by Liu Jingshan (刘金山), then by Sun Lutang’s daughter, Sun Jian Yun.
Sun Jian Yun dedicated her life to preserving her father’s teachings. Li Yulin, father of Li Tianji and grandfather of Li Deyin, was a close disciple of Sun Lutang, and all three (father, son, grandson) have carried on the tradition as well.
My list of the movements in the Sun long form is derived from the book and the names given in the first video above. Where the two lists diverge, I have followed the video; footnotes in the book indicate that Sun’s form continued to evolve after he published the book.

My daily backyard practice in 2021 begins with the Sun 98. I learned the elements of Sun style from Grandmaster Aiping Cheng in 2020, and learned the 98 using Grandmaster Jesse Tsao’s instructional video (available on Taichihealthways.com).
I love the gentleness and accessibility of this style of tai chi; it’s perfect for an ordinary (and older) practitioner like me. These days, a modern competition form in Sun style, the Sun 73, seems to be more widely practiced than the old form. More on that next.
