Who can understand this obscure joke?

A lady sitting on the stage got pregnant unexpectedly. At first, she didn't know, but later, she thought it would be good to have a child to raise, so as to save trouble in the future and provide for herself. I was pregnant in October and gave birth to a boy. Miss is so happy!

After a while, the young lady decided to give the child a name, so the trouble came. Why? Because the young lady doesn't know who the father of the child is and what the child's last name is. Without a last name, how do you name it? Miss is so worried. At this time, one of the young ladies' sisters had an idea and said, The gentleman you often accompany is a professor of liberal arts. Why don't you ask him to help you name it? Miss a listen to overjoyed!

A few days later, the professor came to entertain the young lady. After hearing her request, he agreed on the spot, thinking: this is not a piece of cake for me! But after listening to the young lady's words, I am also very worried: I don't know what the child's surname is, how to choose a name! So I chatted with this lady with the idea of giving it a try.

Professor: Do you remember the approximate date of the child?

Miss: What day should it be today?

Professor: Do you remember who you had sex with that day?

Miss: let me see ... it should be with three people, but I don't know whose children it is!

Professor: Do you remember who they are?

Miss: It should be ... a secretary Gao, a manager Li and a factory director Chen.

.......

The professor pondered for a long time and suddenly patted his thigh: Yes! Child's surname is available! The child should be surnamed Guo!

The young lady was puzzled and quickly asked, why do you want to be surnamed Guo? The professor said that when you have sex with Gao, Li and Chen, you take the upper part of Gao, the lower part of Li and the left part of Chen to form a word. Isn't that Guo? And Chen Dou have contributed to your children. Isn't it fair to take part of their surnames as your children's surnames? The child's surname is Guo! Miss a listen to, that's right! The child's surname is Guo! That's settled. The child's surname is Guo.

You still have to be famous if you have a surname, so the young lady continued to ask the professor to name the child. The professor asked: What's your name? Miss said: Three words, most people in China are three-word names. The professor pondered for a moment, then had a brainwave and said: The second word is "Spring"! The young lady asked, How can I put it? The professor said, what do you think? You had sex with three Republicans that day, which means you were married by three people. Isn't that the word "spring"? Hearing this, the young lady patted the professor and said in a charming voice, you are good or bad! But the word "spring" is quite appropriate. So the second word of the child's name is spring.

Then, to the third word. The professor thought for a moment and said, it's the sea! Without waiting for the young lady to ask why, he went on to say that all three people contributed a little to the birth of the child. It can be said that "three people each contributed a little." Haha, it's "Hai", and the child's name is Guo Chunhai! ! !

So, this child is called Guo Chunhai!
