I first learned Chen double sabers two-three years ago at Master Gohring’s school. I’m reviewing it now with the help of a series of YouTube videos by Chen Zhenglei. Here he is doing the whole form:
Here is my final list of Shuang-Dao Names, derived from multiple sources as well as my own translation. The Chinese and Pinyin are certainly correct; the English translations are as usual all over the map. I’ve settled on fairly literal, simple English. I think it’s easier to just learn the Chinese.

Chen Zhenglei has also made a tutorial consisting of 8 short videos, each covering a few of the 35 moves.
I also have Jesse Tsao’s instructional video (available here), which is in English and well worth the small cost. When I worked my way through the form in 2015, I also used the long, two-part tutorial by Master Tzu Tian Cai. It’s in Chinese with some English subtitles and rewards patience with very clear footwork and swordplay for every move.
Here’s the link for all my posts (notes) on this form, but the resources in this post cover everything I found useful. The version I’ve arrived at this time around is a little different from what we learned in class; it now agrees with Chen Zhenglei , Jesse Tsao, and Tzu Tian Cai.
