The first antithetical couplet: at the beginning, it describes what Wang Chun saw: the capital fell, and the city was ruined. Although the mountains and rivers remain the same, there are grass everywhere and trees are gray. A word "broken" shows the broken scene of the city, which is shocking, and another word "deep" reproduces the barren scene of vegetation, which makes people feel sad everywhere. The author writes about the scenery with emotion, which includes the poet's feelings of worrying about the country and the people and hurting the country.
