Sell the rich but not the poor
Selling the rich and the poor is a Chinese idiom. Pinyin is m à if à ch à P í n, which means that for the rich, they will be exempted from duty if they get money; for the poor, they will be arbitrarily imposed labor. It's from the second moment of surprise.
The origin of Idioms
The 16th volume of Ling Mengchu's second moment of surprise: "I only say that in the world of Yang, corrupt officials suffer from wealth, pervert the law, and sell the rich to the poor. I don't know that the underworld is also like this!"
Idiom usage
Used as predicate, attributive, or object; used of social phenomena. In the draft of the history of the Qing Dynasty, Shi Huo Zhi: "please instruct the officials to pass through the two prefectures and serve according to the fields, so that they can not be rewarded without money in order to alleviate the disadvantages."
