圓

有三圓，即
一。脊背要圓，其力催身，則尾閭中正，精神貫頂。
二。前胸要圓，兩肘力全，心窩微收，呼吸通順。
三。虎口要圓，勇猛外宣，則手有裹抱力。
是謂之三圓。

李存義

"Round. The three things that must be round are:
a) The back should be round. Its strenght breaks the opponent's body, and the sacrum will be centered and upright.The spirit of vitality will permeate to the top of the head,
b) The chest must be round. Then both elbow will be completely strong, the heart cavity slightly contracts, breathing is unhindered and smooth.
c) The tiger's mouth must be round. Then bravery and fierceness will be proclaimed. Then the hands will be able to embrace.
These are the three things that must be round."
