有個叫韋固的人，有一次路過宋城，天黑便投宿一家客棧。半夜時，韋固起身去茅廁，上完茅廁經過院子，看到一位老人在月光下翻著一本厚厚的書，韋固便走過去並問：「這麼晚了，您在看什麼書？」，老人回答說：「這是天上男女的姻緣冊子。」又看到一個大袋子，便問：「這裡面裝什麼？」老人說：「裝的是紅線，兩端用來綁在男女雙方的腳上，如此便會成為夫妻。」韋固聽了半信半疑。這時天亮了，老人便起身往外走，韋固也趕緊跟在後面。
老人走到鬧市中，迎面走來一位瞎眼的婦人，手上還抱著一個大約三歲的女孩子，老人回頭對韋固說：「那個小女孩是你的妻子。」韋固十分生氣，便對跑來的僕人說：「去把那個小女孩刺死！」十四年後，韋固娶了相州刺史王泰的女兒，長得十分美麗，可惜額頭上有個疤，只好戴金花來遮住，韋固便問妻子疤的由來，才知道妻子就是當年被瞎眼奶娘抱著的小女孩，韋固便把當年月下老人的事告訴妻子，夫妻從此更加恩愛。
宋城的縣官知道這件奇事，便將韋固當天住宿的客店命名為「定婚店」。
There was once a man named Wei Gu. One day, Wei Gu passed by Song City. It was getting dark, so he decided to stay at an inn. In the middle of the night, Wei Gu got up to go to the toilet. After going to the toilet, Wei Gu passed by the courtyard. He saw an old man standing in the moonlight. The old man was flipping through a thick book. Wei Gu walked over to the old man and asked curiously, “It is so late, what book are you reading?” The old man answered, “This is the heavenly book that records all marriages between men and women.” Wei Gu saw a large sack on the floor next to the old man and asked, “What is in this sack?” The old man said, “It contains red cords to bind the feet of people who are destined to marry each other.” Wei Gu was not convinced. Dawn came, and the old man got up and walked out of the inn. Wei Gu decided to follow him around.
As they approached the city center, they saw a blind woman carrying a little gir who was about three years old. The old man turned and told Wei Gu, “This little girl will be your wife.” Wei Gu became angry as he did not want to marry a blind woman’s daughter. So, he told his servant, “Go kill the little girl!”
Fourteen years passed. Wei Gu married the daughter of the Governor of Xiang Prefecture. She was noble and very beautiful, but she had a scar on her forehead, which she hid behind a golden flower. When Wei Gu asked his wife about the scar, he learned that she was the little girl that the blind woman was carrying, and that the blind woman was her nanny. Wei Gu was surprised to hear her story, and told his wife about the old man under the moon. They finally believed the old man under the moon, and loved each other even more.
When the County Magistrate of Song City heard about the amazing story, he found the inn that Wei Gu stayed in, and renamed it the “Red Cords Inn.”
