Is it midnight cock crow or midnight cock crow? Please elaborate!

It's a long story Let's start with it. It is said that Zhou Paipi is a wife-shy person. The wife said he didn't dare to be three, and the wife said he didn't dare to be six. And Zhou Paipi's wife is an ugly bitch with a pie face, a single eyelid and swollen eyes. She looks Korean. Zhou skinned really couldn't bear to talk to his wife mournfully. Even when the lights were turned off, I vaguely felt that his wife's face was glowing green. Zhou scalping is also a human being ~ and also has the most primitive desire of human beings, so he had the idea of calling chickens. Out of fear of his wife, he didn't dare to crow openly. So he joined a large group of farmers and made up a story about learning crows at midnight. In fact, Zhou skinned his wife to crow in the middle of the night! Every time a chicken crows, he goes home at dawn, and he will proudly say that he wants to crow like a chicken and urge the workers to get up early to work. His wife believed it every time ~ ~ ~ Later, this story came up with an allusion called "Cockcrow at midnight" ~ Because it was in feudal society, this idiom is hard to say. A man named Jia Fuguier had a brainwave and came up with the proverb "Chicken crows in the middle of the night" ~ Well, that's all for today's class. See you next time.
