Gong Jing dreamed of comets. Where is the origin of this fable?

Gong Jing dreamed of comets. The next day, I summoned Yan Zi and asked him: I heard that the place where the comet appeared will definitely die. Dreaming of a comet at night, I want to summon the dreamer and ask him to divine. Yan Zi replied: "The king lived an unrestrained life, dressed inappropriately, did not listen to outspoken advice, built a lot of buildings endlessly, and was not satisfied with collecting taxes, which made the people overwhelmed." People resent that comets will soon appear in dreams, not just comets.

Gong Jing dreamed of comets. Tomorrow, Yan Zi was summoned and asked, "I heard that those who have comets will die. I dream of comets at night, and I want people called dreams to possess them. " Yan Zi said to him, "You live in a lawless place, your clothes are extravagant, and you don't listen to the right advice. You are idle and insatiable, so that the people will be invincible, the people will complain, and the stars will see dreams. You are a comet alone! "
