This sentence comes from Li Bai's Preface to the Spring Banquet of Peach and Plum Gardens, which means that space is the hostel for all things, and time is a passer-by for hundreds of generations. In other words, life is like a journey, short and uncertain, and only death is the real destination and destination. Therefore, in the journey of life, we must eat, drink, and be merry in time. You can't make up for it if you miss it.

The husband of heaven and earth, the inverse of everything; Time flies, and a hundred generations have passed. And floating like a dream, for geometry? The ancients walked by candlelight at night, good!

Kuang Yangchun called me and said that my friend's article was cigarettes and fake. Will be full of peaches and plums, family happiness. League season is the season of Huilian; We sing, and we are ashamed of leisure. You didn't get a reward. You can tell me. There is a banquet to sit on flowers. Fly on the moon and get drunk. If there is no masterpiece, why Shen Yahuai? If the poem fails, it will be punished according to the number of wines in Jingu.
