The changes that have taken place over thousands of years are vivid. Raise a glass, lean on the virtual wind and lament that the heroes of the ages have quietly gone with the rolling history. Think about it, Emperor Wu of the Han Dynasty drilled a pool for the southwest thoroughfare to practice the water army; Emperor Tang conferred the Nanzhao iron column and carved merits; Song Taizu waved Yufu to demarcate the border and let Dali be autonomous; Yuan Shizu kayaked across the Jinsha River and occupied Yunnan. Alas, this magnificent sight exhausted the hero's efforts to move mountains. All this, like clouds in the morning, lingers outside the curtains of the colorful building. Before the bead curtain rolled up, it disappeared in the yellow rain rustling. These beautiful words and phrases about Song Ji's advantages and virtues are buried in the smoke of sunset farmers with the disappearance of those broken monuments. Alas, we are left with only the scattered bells in the temple and the lights of fishermen by the river. Two rows of autumn geese fly south to the sky, and the mountain dreams after the frost is clear.
