Life is like a dream, flowers bloom at dusk; Going back in time is just a drop in the ocean.
Time is a passer-by for hundreds of generations. Li Bai's Preface to the Garden of Peach and Plum for the Spring Banquet
Life between heaven and earth, if it is a blink of an eye, it is only sudden. Zhuangzi zhibei tour
Life is a difficult journey, you and I are both passers-by, just like stopping at different hotels. -Su Shi Linjiang Xian
