"The Song of the Water Dragon: Nostalgia of the West Lake"

Southeast The first state, West Lake has been beautiful since ancient times. There are pavilions and pavilions near the embankment, with painted boats and pavilions, and tourists singing and playing. There are lotus flowers for ten miles, osmanthus seeds for three autumns, and green mountains all around. It took a hundred years for the heroes to travel south, but they all forgot their life ambitions.

It’s a pity that the sky is spinning and changing, who can help me to be ashamed of the past. Climb to Xingsheng, express your feelings about the past and present, and show your heroic spirit. The strong men push the mountains, and the gods move the water to cultivate the mulberry fields. I borrowed the tide of Qiantang to wash away all the tears for you, General Yue shed tears.
