Will the three princes of Fujian-Taiwan temple fair really get into the upper body?

The Three Princes of the Temple Fair in Fujian and Taiwan are just mythical figures in legend and do not exist in the real world.

The legendary three princes are Fuxi, Shennong and Dayu. They once jointly ruled China and unified China in ancient times, and their deeds were praised by the people, so they were called "Three Princes". Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
