This is a poem to send a friend to the northwest frontier. Anxi, the abbreviation of Anxi Duhu, was established by the central government of the Tang Dynasty to govern the western regions, located in Qiuci City (now Kuqa, Xinjiang). The friend named Yuan went to Anxi on the orders of the imperial court. In the Tang Dynasty, most people who traveled westward from Chang 'an saw them off in Weicheng. Weicheng is the old city of Xianyang, Qin Dou, in the northwest of Chang 'an, on the north bank of Weishui.
Second, what kind of feelings is expressed by a glass of wine in "Advise Jun to drink more wine, Westerners have no reason to go out"?
"There is no reason to persuade you to drink more, and there is no reason to go abroad" is a whole. If you want to deeply understand the deep feelings contained in this parting exhortation, you can't help but involve "going to the West to get through Yangguan". Yangguan, located at the western end of Hexi Corridor, is opposite to Yumenguan in the north. Since the Han dynasty, it has been the channel for the mainland to go out of the western regions. The national strength of the Tang Dynasty was strong, and there were frequent exchanges between the mainland and the western regions. Joining the army or going to Yangguan is a desirable feat in the eyes of the prosperous Tang people. But at that time, the western part of Yangguan was still poor and barren, and the scenery was very different from that of the mainland. Although it is a feat, my friend's "going out to the west" can't help but go through the long March and prepare for the hardships and loneliness of going alone. Therefore, when he left, "advise you to drink more wine" was like a cup of nectar full of rich emotions, which soaked all the rich and profound friendship of the poet. There are feelings of parting, deep consideration for the situation and mood of travelers, and cordial wishes for cherishing the road ahead. For the farewell party, persuading the other party to "have more drinks" is not only to let friends take away more friendship, but also to delay the breakup intentionally or unintentionally and let the other party stay for a moment. Does the feeling of "going out of Xiyangguan for no reason" belong only to walkers? Parting, I have a lot to say, but I don't know where to start at the moment. On this occasion, there is often silence. "Advise you to drink more wine" is a way to unconsciously break this silence and express the rich and complicated feelings at the moment. What the poet has not said is much richer than what he has said. In short, although three or four sentences are only moments, they are extremely rich moments.
