兴起稻田数千顷，每于农月，亲度顷亩，分别肥瘠，差为三品，各立文簿，藏之乡县。
He developed several thousand hectares of rice paddies. Every time it was time for farming, Qin Peng personally measured the acres of land, classifying their fertility or infertility into three levels, which were then recorded in an official document and stored in the townships and the county government.
