There was no word good night in ancient China. People usually say, "It's getting late, go to bed early!" Or, "Tomorrow's date, sleep first", or, rest, rest, sleep, sleep, pay attention to safety.
People with high status, such as the emperor, will politely say, "It's getting late, Your Majesty, pay attention to the dragon body." For people who are similar to themselves, they will say, "It's getting late, go to bed early and see you tomorrow."

1, the word good night comes from the west. It has a beautiful western legend, which comes from ancient Greek mythology.
Legend has it that in Zeus' world, "Good night" is a kind angel. She has no love from her parents, no magic, no beauty other than water hibiscus, and even in her little sky, there is no friend who can rely on each other, trust, comfort and cry.
She is always alone, slowly flying away from the horizon, slowly flying away from everyone. She always has a faint smile on her face, full of tenderness, tranquility and tolerance, and always gives her thousands of years of blessings to everyone without reservation. Whenever night falls, I will say good night to the universe
