The Outgoing Hand Wraps Inward, Opens Outward, Penetrates Above, Stands Below, these are the Four Sides; Intercepting Above, Blocking Below, Leading Inward, Leading Outward, these are the Four Corners. The Four Sides & Four Corners combine to become the Eight Signs. The Outgoing Hand has Four Sides & Four Corners, the Moving Hand has Four Yin & Four Yang. The Outgoing Hand is like an Ox Tongue, Striking arrives like entering the tiger’s den, the hand goes like a steel file, the hand returns like a hooked pole. Appearing & disappearing rapidly is marvelous without end.
