As you have read, our Chinese boxing style is known as Feng Shou, meaning 'Hand of the Wind, and this has its connection with the Earl of the Wind' whose name was Feng Po (Pinyin Fengbo). Now in Chinese mythology he is depicted as a very old man with a long flowing white beard, who stands on the green grass of the heavens' highest pinnacle, dressed in a yellow cloak and wearing a red and blue hat. In his hands he holds the open end of a cotton sack, and wherever he points the mouth of the sack, so the wind blows in that direction.
Thus from his exalted position in the heavens he can turn a full circle, and send the winds unhindered across the whole world. If he moves slowly then the wind from the sack will hardly move, so it will feel like the gentleness of a morning breeze, but if he becomes angry or is surprised then he may turn very fast, and the wind will hurtle across the universe to become and create the devastation of a tornado. So don't upset him by becoming aggressive for the one thing he really hates is violence.
No matter what force he may use at any time, you will never see it, although you will see the results of it or its after-effects, like the leaves being tossed around or the grass bending over. In his more serious moods, you may see the roots of a tree being pulled out of the ground, or roofs being torn off houses, or even ships being tossed onto the land as if they were match sticks. He never gives his intentions away so you can never anticipate his actions and as you can never see him, you never know if he is near you or not.
