"Childhood friends", from which allusion?

The idiom "childhood friends" means that there is no suspicion between boys and girls, and they grew up together. It is very common in our daily life. From which allusion?

"Childhood friends" comes from the Long March of the Tang Dynasty poet Li Bai. "When you, my love, ride a bamboo horse, run in circles and throw your childhood. We live together in an alley in Changgan, and we are all young and happy. " "childhood friends" is taken from here and is widely known.

The Long March, Part I

Don? ? Lipper

My hair barely covers my forehead. I am picking flowers and paying by my door. When you, my love, ride a bamboo horse, run in circles and throw your childhood.

We live together in an alley in Qingkan. We are both young and happy. When I was fourteen, I became your wife. I was too shy to laugh.

I bowed my head and went to the dark corner, unwilling to pay attention to your thousands of calls. But at the age of fifteen, I raised my eyebrows and laughed, knowing that no dust can seal our love.

Even to death, I will wait for you in my post, and I will not lose heart in the silent watchtower. When I was sixteen years old, you embarked on a long journey, crossing the Qingtang Canyon full of rocks and swirling water.

Then in the fifth month, I couldn't help it anymore. The ape shouted in the sky. I looked at the place where you walked, your footprints in front of our door, each hidden under the green moss.

Hiding under the moss is too deep to sweep away, and the first autumn wind adds leaves. Now, in the eighth month, yellow butterflies, two by two, are hovering on the grass in our western garden.

Because of all this, my heart is broken, and I am worried that my bright cheeks will fade. Oh, finally, when you come back through three Pa areas, send me a message home in advance! .

I'll pick you up, and I won't mind the distance, all the way to Sha Changfeng.

Explain the meaning of "childhood" and "bamboo horse" first. "Green plum" refers to immature plums in the south, and "bamboo horse" is a "horse" woven with bamboo when children play.

Then how to explain this allusion? In fact, Li Bai's poem Long March reflects the feelings of businessmen and women who miss their husbands. At that time, because I had to do business, I was running around all the year round, with a long journey and inconvenient transportation, and I might encounter many dangers. Every parting between a wife and her husband is painful and sad, and there was no convenient communication tool in ancient times. Therefore, no matter how difficult and dangerous the road ahead is, a woman persevered without hesitation and waded through mountains and rivers to find her husband.

On the surface, childhood friends tells the story of a wife and her husband playing and frolicking when they were young. At that time, the two children did not have any guesses, but when they grew up, they expressed their love for each other. The poem describes their life scenes when they were young, with the aim of depicting their love for each other and their missing for each other now.

Later, people used "childhood friends" to describe the innocent and innocent feelings between two children.
