A very obscure joke, who knows what it means?

A woman walked into the police station and asked a registered comrade, "Comrade, I want to register my child. What should I do? "

A comrade said, "What's your name?"

The woman showed an embarrassed expression and hesitated.

"What's the difficulty? Please say it, maybe we can help. " Asked the policeman.

"Well, that's right. I slept with three men that night. One is Gao, the other is Li, and the other is Chen. I don't know whose child this is. Last name? What should I do? " The woman said in a hurry.

The policeman said, "Don't worry, don't worry, the last name is good. I'll give you a surname, just Guo. "

"Why Guo?" The woman asked incredulously.

The policeman said, "If the surname is Gao, the word' bit by bit' is used above, and the word' zi' is used below. If the surname is Chen, the word' left ear' is used. Isn't that Guo? Three people have a share, and no one is angry. "

"Well, that makes sense. That's fair, but how do you name a surname? " The woman asked.

"I'll give you a word, just call it' spring'." Another policeman interjected.

"Why is it called' Spring'?" The woman asked puzzled again.

The policeman said, "didn't you sleep with three men on the same day?" When the word' spring' is disassembled, it means that three people have the same day. "

"Well, level, very consistent with the scene at that time. But can you help me say another word? " Women say it's a bit pushy.

"Very well, help people to the end, send Buddha to heaven. I will help you with the word' sea'. " Another policeman watching the scene of bustle said.

"What does' sea' mean?" The woman asked puzzled again.

The police comrade said: "The sea was taken apart by everyone, which shows that everyone contributed a little that night."

The woman blushed and said, "The name can completely cover the whole story, and finally it will be clear. Thank you, the child's name is' Guo Chunhai'. "
