This teaching is very good.

Standing: Like Kun Peng, spread your wings, stretch your whole body, stand tall and straight up and down, stand upright and not bend, stand loose, and you can't see the bent parts all over.

Squat: Like a golden snake, the whole body contracts and sits like a bell, especially with its head as low as possible in its arms and its hips as close to its heels as possible, like a ball of thread.

Tightness: it must be like a rock, invulnerable, and all muscles are bulging. It is as hard as a stone.

Song: Just like bean curd residue, a plate of quicksand, the whole body is relaxed, lying like a bow, the whole body is deboned, and one hand is lifted and put down.
