What measures did Sang Hongyang take to solve the problem of Xiongnu's difficulty in using troops and food shortage in successive years, as well as to resettle refugees and consolidate the border defense in Han Dynasty? Sang Hongyang took a measure to solve the problem of Xiongnu's difficulty in using troops and food shortage in successive years, as well as to resettle refugees and consolidate the border defense of Han Dynasty. "Fake commons" means that the government rents official land in the mainland to farmers for farming and collects fake taxes (that is, land rent) from farmers. "Resettlement" means recruiting soldiers to garrison fields and carry out military reclamation. This measure has enabled some farmers who have lost their land to return to the land and engage in agricultural production. On the one hand, a large number of refugees were resettled, which eased the class contradictions brought about by land annexation. On the other hand, a lot of land in the mainland has been reclaimed, and the counties in the northwest border have also been initially developed.
