My memory will be better if I am brave.

I must be brave.

Words must be nice but actions must be flexible.
Inside and outside must be different. Hu Thuc, that is the art of War.

Must hide my strategem carefully.
In and Out must be different.

Never tell my real thoughts If I do not want to be controlled by others.
If I want anything, show that I do not want.

That is Tao Te Ching.
Phenomenon will contradict the Nature.

Tao Te Ching is the first book of the art of War.
Exist and non exist are the basic of Life.
