The wind whirls and thunders, and exercise is like a god. The decay of the true line comes from the big order, so don't become one. As dense as an armory spear and halberd, Shen Feng is stricter than wise water and less polished than Shinan. Its cursive script is circulated, which can be regarded as two kings.
