The grass is green and the horseshoe is sent. The sentence on it is that Jiang Chun refuses to stay and return home.
The Runzhou Camp to Send Judge Li is a seven-character quatrain written by Liu Changqing, a poet in the middle Tang Dynasty. The whole poem uses the emotions endowed by Jiang Chun, grass color and horseshoe to vividly and implicitly express the poet's feelings of farewell to his friends.
"Wan Li's resignation from family matters" means that Judge Li will bid farewell to his family, relatives and friends and go to Runzhou for military affairs not far from Wan Li. What the poet wants to emphasize is: first, the distance of pedestrians; First, the particularity of pedestrians performing official duties is to perform military affairs. This implies the poet's reasons and worries for seeing him off. Because the ancient means of transportation were extremely underdeveloped, even the quickest means of transportation were nothing more than northerners riding horses and southerners taking boats.
Therefore, the ancient distinction often means either "there is no reason for people to go out to Yangguan in the west" or "it is almost as hard for friends to meet is always involved in business". What's more, Judge Li is going to Runzhou, where mountains and rivers are blocked, to "make a fuss". The poet has repeatedly explained that the place where pedestrians go is far away, which further implies that the poet is deeply worried about the uncertain fate of pedestrians.
Liu Changqing (about 726-786) was born in Hejian (now Hebei Province). A famous poet in the Tang Dynasty, who was skilled in five words and was good at five laws, called himself the "Great Wall of Five Words". His works are concise and delicate, but also contain profound meaning, especially the five-rhythm poems, and the seven-rhythm poems are also very good. However, some of his works are criticized for being too thin in content, not broad in scope and slightly similar in words. His works are mainly collected in Liu Suizhou's Poems, and five volumes of his poems are recorded in Complete Tang Poetry.
