What is the moral of Gong Jing's comet dream?

Gong Jing dreamed of comets, which means: Gong Jing dreamed of comets, which means national subjugation.

The next day, Gong Jing summoned Yan Zi and asked him, I heard that the place where the comet appeared must be conquered. 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 out of line, didn't listen to outspoken advice, built a lot of buildings endlessly, and was dissatisfied with tax collection, which made the people overwhelmed." People resent that comets will soon appear in dreams, not just comets.

Watch comets in public. Tomorrow, Yan Zi was summoned and asked, "I heard that those who have comets will die. At night, I saw a comet, and I wanted to call the person who occupied it. " Yan Zi said to him, "You lead an unrestrained life, wear extravagant clothes, don't listen to correct advice, do nothing, and are insatiable, so that the people will be invincible and all the people will complain." The stars will see you again, and the comet will be alone.
