Two years ago, Mo Tingyu went to the north with a sword. Two years later, Su Changan went to Chang'an with his army. The world is too big, and all living beings are like mesons. The rivers and lakes are too deep, and they hurt people everywhere. Swords, swords, books, friends, and so on. How many springs and autumns. Joy, anger, sorrow, joy, what is the reason? The road is two, two, three and a half dollars, dancing swords, reciting poems and talking about parting sorrows. How can life be full of happiness, when will you stop singing songs about wine?
