"I urge you to have another glass of wine, and there will be no old friends when you leave Yangguan in the west" comes from "Send Off the Second Envoy of the Yuan Dynasty to Anxi" by Wang Wei, a poet of the Tang Dynasty.
The whole poem "Send Yuan Er Envoy to Anxi" is as follows: The morning rain in Weicheng is light and dusty, and the guest house is green and the willows are new. I advise you to drink a glass of wine and leave Yangguan in the west without any old friends.
The literal meaning of the poem: The early morning drizzle wets the dust in Weicheng; the green-tiled hotel and the surrounding willow trees look particularly fresh and clear. Please have another drink at the farewell bar; because after you leave Yangguan, you will not see your old friends there.
Appreciation of the whole poem:
The first two sentences of this poem describe the time, place, and environment of farewell, creating a melancholy atmosphere for farewell. In the early morning, the guest houses in Weicheng, the endless post road extending from east to west, the willow trees surrounding the guest houses and on both sides of the post road. All this is a very ordinary sight, but when read, it is picturesque and full of lyrical atmosphere. "Chaoyu" plays an important role here. The rain in the morning didn't last long and stopped just as it moistened the dust. On the road from Chang'an to the west, there are usually cars and horses passing by and dust flying in the sky. But when we were saying goodbye, the morning rain stopped, the weather was clear, and the road looked clean and refreshing. The word "浥" in "浥Qingchen" means moist. It is used very appropriately here, showing that the rain clears the dust but does not wet the road. It is just right, as if God has specially arranged a road for people who travel far. A dusty road. Guesthouses were originally the companions of travelers; willow trees are a symbol of farewell. The author chose these two things intentionally to connect and say goodbye. They are usually always associated with restraint and sadness, showing a mood of ecstasy. But at this moment, because of the morning rain, it has a unique bright and fresh look - "the guest house is green and the willows are new". On weekdays, the road dust is flying, and the willows on the roadside are often shrouded in gray dust mist. Only after a morning rain does it wash out its true green color, so it is called "new", and because of the newness of the willows, it reflects the green color of the guest houses. In short, from the clear sky to the clean roads, from the green guesthouses to the green willows, a picture with fresh and bright colors is formed, providing a typical natural environment for this farewell. This is an affectionate farewell, but it is not an ecstatic farewell. On the contrary, it reveals a light and hopeful mood. Words such as "Qingchen", "Qingqing" and "Xin" have soft and bright sounds, which strengthen the readers' feeling.
Three or four sentences of farewell form a whole. To deeply understand the deep affection contained in this invitation to drink before leaving, we have to involve "Going out of Yangguan from the West". Yangguan is located at the western end of the Hexi Corridor, opposite Yumenguan to the north. Since the Han Dynasty, it has been the passage from the mainland to the Western Regions. The country was strong in the Tang Dynasty, and there were frequent exchanges between the inland and the Western Regions. In addition to joining the army or going on missions to Yangguan, it was a desirable feat in the minds of the people of the prosperous Tang Dynasty. But at that time, the west of Yangguan was still a desolate and desolate area, and the scenery was very different from that in the mainland. My friend, "leaving Yangguan in the West" is a feat, but it will require a long journey of thousands of miles, and you will experience the hardship and loneliness of walking alone in poverty. Therefore, "I urge you to drink another glass of wine" before leaving is like a cup of rich emotional nectar soaked in all the rich and deep friendship of the poet. There is not only a feeling of farewell, but also a deep concern for the situation and mood of the traveler, and a sincere wish to cherish the journey ahead. For the farewell person, persuading the other person to "drink one more glass of wine" not only allows the friend to take away one more point of friendship from him, but also intentionally or unintentionally delays the breakup so that the other person can stay for one more moment. The feeling of "no one knows anyone before leaving Yangguan in the west" is not just for travelers. Parting Yiyi, there is a lot to say, but there are so many things to say that I don’t know where to start. On such occasions, there is often a wordless silence. "Persuading you to drink another glass of wine" is a way to break this silence unconsciously and a way to express the rich and complex emotions at the moment. What the poet has not said is much richer than what has been said. In short, although the three or four sentences cut out only a moment of the scene, it is an extremely rich moment.
