Which poem did childhood friends come from?

The word "childhood friends" comes from Li Bai's Song of Chang Gan. At the beginning of the poem, I recalled their intimate play together since childhood: "When you, my love, rode on a bamboo horse, trotted around in circles and left your childhood behind. We live together in an alley in Changgan, and we are all young and happy. " Later, childhood friends and two children who don't guess were used to express naive and pure long-term deep feelings.

Excerpt from the original:

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 Changgan, and we are both young and happy.

When I was fourteen, I became your wife, and 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.

Song of Chang Gan is a set of poems by Li Bai, a poet in the Tang Dynasty. These two love narrative poems reflect the life and feelings of ancient merchant wives in the form of monologues. It depicts all aspects of women businessmen's life in all stages of their lives, shows vivid pictures, and shapes an artistic image of businessmen who persistently pursue their ideal life and yearn for it.
