The Song of the Arms (臂) in the Nine Songs of Xing Yi Quan (形意拳九歌) by Jiāng Róngqiáo (薑容樵)

臂
左臂前伸，
右臂在肋，
似曲不曲，
似直不直，
過曲不遠，
過直少力。
薑容樵

"The left arm stretches forward.
The right arm is by the ribs.
They seem bent but are not bent.
They seem straight but are not straight.
Bend too much and there is not enough reach.
Make it too straight and there is not enough strength."

From the book Xing Yi Mother Fists (形意母拳), by Jiāng Róngqiáo (薑容樵), based on the translation by Joseph Crandall
