It comes from the preface to the poem "Spring Night Banquet from My Brother's Peach Blossom Garden" by Li Bai, a poet in the Tang Dynasty. The whole sentence is about the husband of heaven and earth, and everything goes against the journey. Time flies, and a hundred generations pass by. And floating life is like a dream, for joy geometry?

In the vernacular, it means that heaven and earth are all things, and all generations are passers-by through the ages. The difference between life and death is just like the difference between dreams and waking up. How much joy can we get from the various changes?
