[Idiom story]

In the Northern Song Dynasty, there was a painter named Sun Zhiwei. He is good at figure painting. On one occasion, he was entrusted by Shouning Temple in Chengdu to draw a picture of a gentleman with nine Yao stars. He carefully hooked the picture with a pen, and the characters were lifelike, the clothes were fluttering and graceful, leaving only the last coloring process. Just then, a friend invited him for a drink. He put down his pen and looked at the painting carefully for a while, feeling very satisfied. He said to his disciples, "I have finished drawing the lines of this painting, only coloring is left." You must be careful not to color it wrong. I have something at my friend's house. I hope you can draw it when I come back. "

After Sun Zhiwei left, the disciples watched the teacher's brushwork and overall composition over and over again around the painting and exchanged ideas with each other.

Someone said, "You see how realistic the demeanor of the plumbing star is. He has a long beard and is not angry and arrogant."

Others said, "The auspicious clouds around the bodhisattva's feet are really awe-inspiring."

One of them is Tong Renyi, who likes to show off his cleverness and grandstanding. He was the only one who pretended not to say anything.

Someone asked him, "Why don't you talk? Is there anything wrong with this painting? "

Tong Renyi pretended to be profound and said, "The teenagers around the plumbing star are very vivid, but there seems to be something missing from the crystal bottle in his hand."

The disciples said, "I didn't find anything missing."

Tong Renyi said: "Every time the teacher draws a bottle, he always draws a flower in it, but this time there is no flower. Maybe we are in a hurry to go out and have no time to draw. Let's draw it first and then color it. "

With that, Tong Renyi carefully drew a gorgeous red lotus flower on the bottle mouth.

Sun Zhiwei came back from a friend's house and found a lotus flower in the bottle in Baryon's hand. He said with anger and laughter, "Who did this stupid thing? If you just gild the lily, it's just self-defeating. The bottle in the boy's hand is a demon bottle used by the water heating star to subdue the water monster. If you add lotus flowers to a vase and turn it into an ordinary vase with flowers, it will be a big joke. " Said, tearing the painting to pieces.

The disciples looked at Tong Renyi and bowed their heads in silence.
