The root of the futility of wick weaving

From ancient legend and folktales in China. "Wick weaving-in vain" is a two-part allegorical saying, which means wasting your mind in vain. In ancient times, there was a scholar named Wang Xiucai. He heard a legend that he could pass the imperial examination as long as he weaved with wick, so he looked around for wick and tried to weave with it, but in the end he found it all in vain. The meaning of this two-part allegorical saying is not only to remind people not to make unnecessary efforts, but also to warn people to distinguish right from wrong, not to believe rumors and not to blindly listen to what others say.
