Modern Li Ao's jingle: "The back waves of the Yangtze River push the front waves, and the front waves die on the beach. When the scenery of Houlang can last, it will be different in a blink of an eye. " The back wave of the Yangtze River pushes the front wave, and the front wave finally disappears on the beach. How long can the waves last? In the blink of an eye, they will disappear on the beach like the previous waves.
