The AYZYIM logo, designed by Andre Zielinski,  depicts a "wind-fire wheel" (風火輪) under each foot of Nezha (哪吒), a Taoist protection deity, the enfant terrible, and trickster, of Chinese mythology.   The wind-fire wheels under Nezha's feet allow him to fly and travel at will.  Like Nezha, a martial artist who excels at the Pre-Heaven Power Method feels his feet vibrating at all times during action as if there are wind-fire wheels under his feet.
