Fourth Secret Song (歌訣四) from the The Thirty-Six Songs of Baguazhang (八卦掌三十六歌)

歌訣四

一勢單邊不足奇，
左右迴圈乃為宜。
左換右兮右換左，
抽身倒步自合機。

"A single sided practice is odd and not worth,
Revolving in circles to both sides is therefore appropriate.
Change from left to right and from right to left,
Draw out the body and step backward to create an opportunity."

Based on the translations by Yang Jwing Ming (楊俊敏) and Liang Shou You (梁守渝) in "Baguazhang - Theory and Applications" (峨嵋八卦掌) and by Frank Allen and Tina Chunna Zhang in "The Whirling Circles of Ba Gua Zhang"
