Heaven and earth are like a shuttle, and the opening and closing of the sun and the moon means that the sun and the moon come and go like a shuttle, describing how time flies. From: Backstreet Record, Volume II: "Weaving Wu, Japan, and going back and forth like a shuttle."

Backstreet Record is an anecdote novel written in classical Chinese by China in Song Dynasty. There are eight volumes. Author Zhao Lingzhi. It is quite accurate to interpret famous things, customs, dialects and classics, and to record people's exchanges, comments, anecdotes and poems, and to seek far-reaching evidence, which has the value of literary historical materials. I can write, too, but the collection has been lost. Some lost poems are scattered in the notes of various factions.
