The story and meaning of the old man under the moon are very short. How does the old man understand under the moon?

1, the old man under the moon, is a famous allusion from the Tang Dynasty. It's a sequel to the mystery book "The betrothal shop" by Li Fuyan, a writer in Tang Dynasty. In the second year of Tang Chaoyuan (AD 807), a scholar named Gu Wei passed by the Song Cheng Inn in Nandian, Song Cheng, and met an old man reading a marriage book in the moonlight at night. Under the moon, the old man pointed out the marriage partner for Wei Gu with a red rope. Later, Gu Wei really married the daughter of Wang Tai, the secretariat of Xiangzhou, according to Yue Lao's words. Because this allusion happened in Nandian, Song Cheng, Li Fuyan, a writer in the Tang Dynasty, named this rumor "betrothal shop" and included it in the book "Continued Mystery Record" (formerly known as "Continued Mystery Record"), which was passed down from generation to generation and known to all men, women and children. The story of "the old man under the moon" originated in the Tang Dynasty, which reflects people's cognitive attitude towards love and marriage.
