On the evening of September 19, inside a performing arts hall of downtown Xiangyang, Wang Xiaoyan, a master of balance, exhibited the stunts of balancing with a feather.

On the stage, Wang Xiaoyan lithely put a feather on a tree branch. Next, more than more tree branches were piled on. A gigantic balance system was formed through the mutual connection of weak touch points one by one.

Finally, in dead silence, Wang Xiaoyan picked the feather, causing the giant balance system to collapse in a moment. The skeleton fell to the ground in pieces. It showed popular science - as long as there is the light feature, the skeleton remains intact; as long as the light feather falls, the skeleton is scattered in pieces.
