What do you mean, only state officials can set fires, and people are not allowed to turn on the lights?

"Only state officials are allowed to set fires and people are not allowed to light lamps" means that rulers can do evil, and the legitimate words and deeds of the people are also subject to various restrictions. A friendship between gentlemen is as light as water, but a friendship between villains is as sweet as water. In other words, the friendship between gentlemen is dull, while the friendship between villains is as thick as wine. Smart and eager to learn, not shy to ask people with lower status and less knowledge than themselves.
