1. Outside triangle stepping to gaizhang, also called whirlwind palm (description for right gaizhang). Step back slightly into the corner of a triangle in a T step and sweep the left hand down, hooking past the knee, hooking back the right hand behind the body. Step a baibu across to the other corner of the triangle and sweep the left hand up, attaching the right hand through the upper back, so that the arms move together. Step forward onto the apex of the triangle and pull the left hand in to under the right elbow or lower, bringing the right hand through past the ear to gaizhang. The line is set up on the previous stretch, so the hand comes through on that line naturally to strike. Use stable stepping and body power - not just the arms. Keep the body upright, do not lean when you step. This large stepping drill develops the spirit of the dragon, which won't let anything get away but will always chase. Do the whole move at once without a pause (but do not rush). Concentrate on the stepping - it must be stable with the body upright. If you turn a car on two wheels it will flip over - don't spin around the arms like a wheel on an angle.
You can also do the outside triangle stepping drill to an elbow strike. The stepping, power and setup is similar to gaizhang, but you bend the arm to come through to strike with the elbow.
2. Zigzag straight line stepping with gaizhang. Simple baibu and arm sweep, connecting the arms through the upper back. Then grab and pull, and bring the rear hand through to gaizhang.
3. T pattern stepping, or stepping to four directions. See the description under tanzhang. The stepping pattern is the same. Use the gaizhang arm and body action.
4. Back and forth stepping to gaizhang.
Combinations: gaizhang with fanbeichui.
