A dream with a dream in the yellow beam (pinyin: huá ng liang y Ο mè ng) is an idiom derived from fables, and the related allusions of the idiom originated from A Story on the Pillow written by Shen Jiji in the Tang Dynasty.
According to Sleeping Story, Lu Sheng met Lu Weng, a Taoist priest, at Handan Inn and lamented his poverty. Lu Weng took a celadon pillow to let Lu Sheng sleep, and the shopkeeper was cooking small rice. Lu Sheng enjoyed all the splendor in his dream. When he woke up, the little rice in the shop was not ready yet. According to this story, later generations summed up the idiom "a dream with a cow" (a cow: millet), which is a metaphor for illusory dreams and unattainable desires; Can be used as subject, object and attribute in a sentence; More derogatory.
Origin of idioms
In the seventh year of Kaiyuan, Lu Weng, a Taoist with immortal skills, walked in the middle of Handan Road, rested in the mansion, took a hat and sat in a hidden bag. I met the teenagers on the journey, but Lu Sheng also. ..... Lu Sheng realized that he was lying beside him in the mansion, and Lu Weng was sitting beside him. The steamed millet was not ripe, and he felt almost the same. However, Jǔe was very happy. He said, "Is this a dream?"
Weng said: "Life is appropriate, so it is appropriate." After a long time, Xie Yue said, "I know the way my husband was humiliated, my poor luck, my sense of loss, and my feelings about death and life. This gentleman strangled my desire. Dare not be taught! " The kotow bowed again and left. (Don Shen Jiji's Pillow Book)?
According to this story, later generations refined idioms such as "Fool's Dream", "Fool's Dream" and "Fool's Pillow".
