During the Song Dynasty, there was a painter named Sun Zhiwei. Once he was commissioned by the Shouning Temple in Chengdu to paint a picture of the "Nine Star Gods". He sketched the picture with a brush, and the figures were lifelike, with floating clothes and sashes, just like immortal postures, and only the last process of coloring remained. He put down the brush and looked at the painting carefully for a while, feeling satisfied, and said to his disciples, "I have drawn all the lines of this painting, only the coloring remains, you must be careful not to get the colors wrong, I have to go to a friend's house for something, when I come back, I hope you paint well."
After Sun Zhiwei left, the disciples gathered around the painting and repeatedly watched the skill of the teacher's brushwork and the mastery of the overall composition, exchanging ideas with each other.
Some said, "Look at how realistic the appearance of the water-warming star-king is, with its long beard and unruffled authority."
Others said, "The auspicious clouds under the Bodhisattva's feet are so comprehensive, truly divine and immortal, that people stand in awe."
One of the disciples named Tong Ren Yi, who usually specialized in showing off his small cleverness and liked to clam up, was the only one who pretended not to say a word.
Someone asked him, "Why don't you say anything, could it be that there is something missing in this painting?"
Tong Ren Yi said in a pretentious manner, "The child beside the water-warming star ruler is very evocative, but the crystal bottle in his hand seems to be missing something."
The disciples said, "I didn't find anything missing."
Tong Ren Yi said, "Every time the teacher draws a bottle, he always draws a flower in the bottle, but this time there is none. Maybe he was in a hurry to go out, so he didn't have time to paint it well, so let's paint it well and color it."
Tong Renyi said, and drew a bright red lotus flower in the mouth of the bottle with his heart.
Sun Zhiwei came back from a friend's house and found that the bottle in the child's hand had a lotus flower, and said with anger and laughter, "Who did this stupid thing? The bottle in the hands of the child, is the water warming star used to subdue the water monster demon bottle, you add a lotus flower, the treasure bottle into an ordinary bottle containing flowers, will not be a big joke." Saying that, the painting tore to pieces. The disciples looked at Tong Ren Yi, silently bowed their heads and did not speak.
