After clearly understanding the Three Sections, the Five Jins mutually support each other. Stamping, Pouncing, Wrapping, Binding, but only Bursting must be correct.
五勁者，踩撲裹束決。踩勁如踩毒物也。 撲勁如兔虎之撲也。裹勁如裹物而不露也 束勁如上下束而為一也。決勁如水決也。踩要決，撲要決，裹要決，束要決, 決要決。一決而無不決，非決而不靈也。
The Five Jins are Stamping, Pouncing, Wrapping, Binding, & Bursting. Stamping Jin is like stepping on a poisonous creature. Pouncing Jin is like a tiger attacking a rabbit. Wrapping Jin is like wrapping something so nothing is exposed. Binding Jin is controlling upper & lower as one. Bursting Jin is like water breaching a dam. Stamping must have Bursting, Pouncing must have Bursting, Wrapping must have Bursting, Binding must have Bursting, and Bursting must have Bursting. All have Bursting & none lack Bursting. To lack Bursting is to be ineffective.
