The original note of this poem: "That was seventeen years old." Explain that this is the work of Wang Wei's Seventeen Points. Wang Wei was wandering between Luoyang and Chang 'an alone. He is from Zhou Pu (now Yongji, Shaanxi Province), and Zhou Pu is in the east of Huashan Mountain, so he called his hometown brothers Shandong brothers. September 9th is the Double Ninth Festival, and some places in China have the custom of climbing mountains. The thirty-second volume of "Peaceful Magnolia" quoted a local custom story and said: "This day is established by convention and matured with the strong spirit of Cornus officinalis. On this day, the folded house is blocked to prevent early cold. "

There is a custom of climbing mountains on the Double Ninth Festival. It is said that wearing a dogwood bag when climbing a mountain can avoid disaster. Cornus officinalis, also known as Moongum, is an aromatic plant. In three or four sentences, if we just think about how brothers climb mountains and wear dogwood in the Double Ninth Festival, but they are alone in a foreign land and can't participate, although they write about their homesickness in the festival, they will appear straightforward and lack freshness and affection.

The poet thought in the distance: "There is one person missing from the dogwood." Brothers far away from home all wore horns when climbing the mountain today, only to find that one brother was missing-he was not among them. It seems that it is not a pity that I failed to spend the holidays with my brothers in my hometown, but that my brothers failed to reunite completely during the holidays;

It seems that it is not worth saying that a person is a stranger in a foreign land, but the shortcomings of brothers need to be understood. This is tortuous and unnatural. And this unusual place is precisely its deep place, where the new police world lies. Du Fu's Moonlit Night: "For our boys and girls, poor little babies, it's too young to know where the capital is" is similar to these two sentences, but Wang Shi doesn't seem to be so focused.
