Poem of Zhang Xiumu
Lai (Zhide)´s Tai-chi is the principle of Quan,
A single line runs through Heaven, Man and Earth.
Noumenon of Tai-chi is the innate Qi,
Dividing yin and yang form postnatal body.
Strategy to opponent attrack is magic number one (unitary Qi),
Flowing Qi comes from the centre cavity.
Training way is the practice of the innate Bei Si Kuo,
Tao triggers creation and transformation, changes unlimited.
