What does it mean to be willing to report a new color before leaving your job?

This sentence is selected from Xie Qian's Hate in Spring. Xie Qian was promoted by Prime Minister wang pu. Later, wang pu was sentenced to death in prison, and he was also implicated and demoted. This poem was written after he was demoted.

Yongxiang often heard about the small garden, and it was difficult to accept the old kindness of tears. You are willing to report the new color first, and the round fan must protect the white dew.

The author is willing to be emperor for the country.

The round fan must be protected from the white dew and autumn, which means that after summer, when the weather gets cold, the round fan will be put away, just like himself. Times have changed, and birds have tried their best to hide. It is the author who laments that the emperor is unfair to himself and should not relegate himself.

I insist, I hope you can adopt it, thank you.
