There is also a saying from Yunwu Valley and Menggu, is it a famous saying that has been bothering Yueyang City?

First of all, this poem was not written by Du Fu, but from Meng Haoran's Dongting Lake to Prime Minister Zhang. "Cloudy dream fog, trapped Yueyang City" is written about the water vapor transpiration of Yunmengze, and Yueyang City is shaken by the waves of Dongting Lake. The sentence pattern is neat and the artistic conception is smart, showing a magnificent momentum. A word "steaming" describes the trend of cloud steaming, dragon leaping and tiger leaping, and galloping horses. The word "shake" is like a scene where huge waves fly, "lapping the shore and rolling up thousands of piles of snow". Yueyang City, on the other hand, is surrounded by magnificent lakes, which makes readers compare with things: an ancient city is still so small compared with the vast lakes, not to mention the strength of one person. Without the protection and nourishment of lakes, there would be no grassland.
