The story of "Give someone a rose, and there is a lingering fragrance in your hand"
It is said that once, Wang Xizhi passed a bridge in Yin Shan. An old woman went to a charity sale with a basket of hexagonal bamboo fans. That kind of bamboo fan is very simple, without any decoration, which can't attract the interest of passers-by. It seems that it can't be sold, and the old woman is very anxious.
Seeing this situation, Wang Xizhi felt sorry for the old woman, so he went up to her and said, "You can't sell this bamboo fan because there are no pictures or words on it." How about I write an inscription for you? " The old woman doesn't know Wang Xizhi. Seeing his enthusiasm, she wrote him a bamboo fan. Wang Xizhi took a pen, wrote five words on each fan and gave them back to the old woman.
The old woman can't read, and she feels that his handwriting is scrawled, so she is very unhappy. Wang Xizhi comforted her and said, "Don't worry. You told the fan buyer that it was written by Wang Youjun. " As soon as Wang Xizhi left, the old woman did as he said. Collectors rushed to buy Wang Youjun's calligraphy after seeing it. A basket of bamboo fans soon sold out.
