The Song of Peng

What is the meaning of Peng energy?
It is like the water supporting a moving boat.
First sink the ch’i to the tan-t’ien,
then hold the head as if suspended from above.
The entire body is filled with springlike energy,
opening and closing in a very quick moment.
Even if the opponent uses a thousand pounds of force,
he can be uprooted and made to float without difficulty. (more…)

Be conscientious in Peng, Lu, Chi, and An.

Upper and lower coordinate,
and the opponent finds it difficult to penetrate.

Let the opponent attack with great force;
use four ounces to deflect a thousand pounds.

Attract to emptiness and discharge;
Chan, Lien, T’ieh, Sui,
attach without losing the attachment.

If the spirit cannot reach the headtop, it cannot raise. (more…)
