The cultural relics of the Six Dynasties are scattered all over the sky, and the sky is light and the clouds are clear.
Du Mu of the Tang Dynasty "Inscribed on the Water Pavilion of Kaiyuan Temple in Xuanzhou, Your Excellency Wanxi River, and the People Living in Jiaxi River". Six Dynasties: refers to the Eastern Wu, Eastern Jin, Song, Qi, Liang, and Chen. The general meaning of these two sentences is: the cultural relics of the Six Dynasties have long since disappeared, and only the grass is in the sky; the scene of light clouds that day is the same in ancient and modern times. Kaiyuan Temple is a scenic spot in Xuanzhou (now Xuancheng, Anhui). The poet often came here to enjoy it when he was a judge of the Xuanzhou regiment. These two sentences create a strong lyrical atmosphere with the ancient and modern associations evoked by the poet when he climbed up to view the scenery. The prosperity of the Six Dynasties has become a trace. Looking around, I can only see the color of grass in the sky, the sky is high and the clouds are pale. I can only feel the vicissitudes of human life. Only the natural scenery and the four seasons have not changed much since ancient times. The poet's writing style is indifferent and his artistic conception is profound, which arouses endless reverie and can be used to express nostalgia for the past.
