Tell me why Emperor Taizong didn't adopt the writer's suggestion.

1. He believes that honesty should be used to govern the world, not fraud, which is the enlightenment of a generation of wise kings.

2. Analysis:

Regarding the request of "please go to the courtier if you have written a letter", Emperor Taizong said, "I want to make great faith work in the world, and I don't want to cheat people. Although your words are good, I don't take them." His answer shows that he believes that the world should be governed by honesty, not by fraud, which is the enlightened place of a generation of wise kings.
