The lush vegetation contrasts with the desolation, to express the emotions of ups and downs. For example, "The spring breeze has passed for ten miles, and all the shepherds and wheat are green." (Jiang Kui Yangzhou Man) The spring breeze has spread for ten miles, and the very prosperous Yangzhou Road is now long. It was full of green buckwheat, and the whole area was desolate. "The willows on the deserted platform of the old garden are new, and the singing of water chestnuts is so beautiful in spring." The willows on the deserted platform of the old garden of Wu State have grown new branches again (a desolate place). I recall that there were singing and dancing here. , the grand scene is more beautiful than the spring scenery (not as good as the spring: the spring scenery is not as good as it). Here, the lush willows set off the desolation.
"The green grass in front of the steps is full of spring, and the oriole's voice is heard in the sky through the leaves." (Du Fu Prime Minister of Shu) A generation of virtuous ministers and their achievements have disappeared. Now there is only the green grass reflecting the green stone steps, which produces spring scenery every year (the spring light is in vain), and the oriole makes this melodious and beautiful call in vain. The poet laments that the past is empty and empty. Expressing regret.
"The grass and flowers beside the Zhuque Bridge, the sunset is setting at the entrance of Wuyi Lane." (Liu Yuxi Wuyi Lane) The former prosperity beside the Zhuque Bridge has disappeared, and the bridge has been covered with weeds and wild flowers. Wuyi Alley has lost its former splendor, and the setting sun reflects the dilapidated and desolate alley.
