Furong Building was originally named Northwest Building, and the site is in the northwest of Runzhou (now Zhenjiang, Jiangsu). Boarding can overlook the Yangtze River and overlook the north of the Yangtze River. This poem was written about twenty-nine years after Kaiyuan. Wang Changling was Cheng of Jiangning (now Nanjing) at that time, and Xin gradually was his friend. This time, he plans to cross the river from Runzhou, via Yangzhou, and go north to Luoyang. Wang Changling may accompany him from Jiangning to Runzhou, and then break up here. The original title of this poem is * * *. The second poem talks about the poet's farewell ceremony for Xin Xian in Furong Building the night before, and this poem is about the scene of leaving by the river the next morning.

"Cold rain enters Wu at night even in the river", misty rain hangs over the river in Wu, weaving an endless network of worries. The rainy night adds to the bleak autumn, and also renders the gloomy atmosphere of parting. That chill not only pervades the misty rain in the boundless river, but also permeates the hearts of two people who have left. The word "Lian" and the word "Jin" describe the steady and continuous rain, and the dynamic coming from the river rain can be clearly perceived by people, so it is conceivable that the poet stayed up all night because of his feelings. However, this picture of the night rain in Wujiang, which is connected by water and sky, does not show an extremely lofty and magnificent realm? In the middle and late Tang poetry and graceful Song poetry, the sound of rain was often written on such trivial things as phoenix tree under the window, iron horse in front of eaves, residual lotus in the pool, etc. However, Wang Changling didn't really write the details of how to perceive the coming of autumn rain. He just summarized the auditory vision and imagination into the rain of Lianjiang into Wu, and dyed a lot of misty rain with a large piece of light ink, which set off the open artistic conception of "seeing off the guests in plain and bright, and seeing off the lonely mountain in Chu" with great boldness of vision.

Early in the morning, it was already dawn, and Xin gradually was about to board a boat and return to the north. Looking at the distant mountains in the north of the Yangtze River, the poet felt lonely when he thought that pedestrians would soon disappear outside the Chushan Mountain. On the vast river, of course, it is not only the solitary Chu Mountain that enters the poet's field of vision, but the mighty river is originally the most likely to arouse the association of feelings like water, and the famous sentences obtained by the Tang people are countless. Wang Changling, however, did not place his sorrow on the river that went away with his friends, but focused his parting on the Chushan Mountain, which stands in the vast Ping Ye. Because friends can get together with relatives and friends when they return to Luoyang, the poets who stay in Wudi can only stand by the river and watch the flowing water pass away like this lonely Chushan. A word "lonely" is like a fuse of feelings, which naturally leads to the last two parting words: "Luoyang relatives and friends are like asking each other, and a piece of ice is in the jade pot."

As early as the Six Dynasties, Liu Song Dynasty, the poet Bao Zhao used "as clear as a jade pot of ice" ("Songs of the White Head") to describe the noble and innocent character. Since Yao Chong, the prime minister of Kaiyuan, wrote Curse of Curling, poets in the prosperous Tang Dynasty, such as Wang Wei, Cui Hao and Li Bai, have encouraged themselves by curling, praising the character of being open and aboveboard. The message that Wang Changling Tuoxin gradually brought to relatives and friends in Luoyang was not the usual peaceful bamboo newspaper, but conveyed his belief that he was still clean and honest, which was of great significance. According to Biography of Talented Talents in Tang Dynasty and Collection of Tales of Heroes in He Yue, Wang Changling was once exiled to Lingnan for the first time in the 27th year of Kaiyuan because of his informality. After returning from Lingnan, he was appointed as Jiangning Cheng, and a few years later he was relegated to Longbiao, which shows that he was in a bad environment destroyed by oral sex. Here, the poet refers to himself as a crystal clear ice heart jade pot, which is based on the real understanding and mutual trust between him and his friends and relatives in Luoyang. This is by no means a confession to wash away the slander, but a self-esteem to despise slander. Therefore, the poet holds out a bright and pure ice heart from the flawless and empty jade pot to comfort his friends, which can better express his deep affection for relatives and friends in Luoyang than any words of acacia.

Emotion comes from the scene, and emotion is contained in the scene. This is the same characteristic of Tang poetry, but it is profound, soft and soothing. "Thanks for the trace of the furnace hammer" (Hu Yinglin's Poems) is another unique style of Wang's poems. The boundless river rain and solitary Chu Mountain in this poem not only set off the poet's cold and lonely feelings when he bid farewell, but also showed the poet's cheerful mind and strong character. The lonely mountain standing in the middle of the river and the image of Bing Xin placed in the jade pot form a kind of intentional or unintentional care, which naturally reminds people of the poet's image of being lonely and proud, pure and clean, and melts the exquisite conception and profound intention into the artistic conception of emptying Ming Che, so it is naturally muddy, with no trace, implicit implication and endless aftertaste.
