The world is not pure land, each has its own sufferings, and we are all sad guests in the world of mortals. Don't laugh at who is poor! The rising sun warms the sun, and the years are quiet! The years are quiet and good, which comes from The Book of Songs, the national style of Zheng Feng's "Women Say Chicken Crow". The original sentence is "the harp is in the imperial palace, so it is quiet and good."

The national wind crows is a poem in The Book of Songs, the first collection of poems in ancient China. Most modern scholars think this is a poem praising the harmonious life, sincere feelings and beautiful life wishes of young couples.
