The origin of Idioms
Zhang Juzheng's answer to tan Erhua's book of Kaifu in the middle of Sichuan Province in the Ming Dynasty: "the people of the neighboring areas of Sichuan are rugged and easy to move. Most of them are pacified when they are appeased, disordered when they are disturbed, lazy when they are bored, and strange when they are anxious when they are frightened."
