What is the story of the idiom self-defeating in history?

The word self-defeating means that I wanted to show off my cleverness and do better, but I did something stupid and made things worse, so this word is generally used as a derogatory predicate in sentences. I wonder if you have a certain understanding of the origin of this idiom. This is an idiom in China, which originated from the Five Lights and Huiyuan. Next, Bian Xiao will tell you what kind of story this idiom tells.

First of all, when reciting, there was a painter named Sun Zhiwei. He is very good at drawing portraits, so once he was entrusted by Shouning Temple in Chengdu to draw a picture of Nine Yao Stars. He painted this painting very well, and all the parts were completed except the final coloring process. Then one of his friends invited him to drink at this time, and he told his disciples to be careful not to let go.

Then, there was an apprentice named Tong Renyi, who usually liked to show off his cleverness and left a deep impression on people. He just pretended not to say a word and pretended to be inscrutable, saying that he thought the boys around the water heater were very vivid, but the crystal bottle in his hand seemed to be missing something. Everyone asked him what he was missing. He said that the teacher always drew a flower in the bottle every time he painted, but there was no flower this time. Maybe he was in a hurry to go out, so let's draw and color it, and then he drew a very gorgeous red lotus on the bottle mouth. Then, when Sun Zhiwei came back from a friend's house, he said with anger and laughter, if we gild the lily, it would be self-defeating, because the bottle in the boy's hand was a demon bottle used to warm the water to subdue the demon, and it was a big joke to treat Aquarius as a vase, so he tore the painting to pieces. Then the disciples looked at Tong Renyi and bowed their heads silently.

Finally, this story also tells us clearly that we should never be smart in life, especially when our ideas and opinions are immature. The more you show off, the more you show off, the more you will show your shallowness and ignorance.
