Eight Secret Song (歌訣八) from the The Thirty-Six Songs of Baguazhang (八卦掌三十六歌)

歌訣八

走時周身莫動搖，
全憑膝下兩相交。
底盤雖講平膝胯，
中盤也要下腿腰。

"When walking, the entire body remains stable.
The whole relies on the knees intersecting.
Although the lower section concerns the leveling of knees, waist and thighs,
The middle section is also dependent on the legs and waist."

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"
