Xi Shi, one of "Four Beauties" in the history, had a pain in her bosom, so she had a frown on her face when she went out. Dong shi is an ugly girl who lived nearby, she saw Xi Shi frowning and thought she looked very beautiful. Therefore, when she went home, she also put her hands on her bosom and had a frown on her face.
When a rich man in the neighborhood saw her, he shut his doors tightly and did not go out. When a poor man saw her, he took his wife and children and gave her a wide berth. She only knew Xi Shi's frown looked beautiful, but she did not know the reason for its beauty.
