Li Bai's Midnight Wu Ge: "A bright moon hangs high in the capital, and it is washed with ten thousand hammers."
Cen Can's poem says, "A solitary lamp illuminates a guest's dream, while a cold pestle smashes homesickness."
Du Fu also wrote Yi Dao: "Even if you don't return, the anvil will be wiped clean in autumn. It's near dusk, the cold moon is in the sky, and the love is long. I'd rather say I'm tired of Yi Dao, but I'll push it to the wall. I will exhaust the power of the boudoir and listen to the voices outside. "
There is also Li Yu's poem "Dao Lianzi": "The deep courtyard is quiet, the small courtyard is empty, the cold anvil is intermittent, and the wind bursts. But people can't sleep at night, and the sound of the moon reaches the curtain. " ("anvil" is a stone anvil used to smash clothes)
