Major achievements

At the end of the Eastern Han Dynasty, the social economy of the Huanghuai River Basin suffered unprecedented destruction, the people were slaughtered, the land was barren, and the survivors were forced to leave their homes and live in exile. It can be said that "the name is empty and uninhabited, and there are no people in a hundred miles", and "the bones are exposed in the wild, and there are no crows in a thousand miles".

Faced with this tragic situation, Cao Cao implemented a series of policies to restore the economy and stabilize the situation before his death. Judging from Cao Cao's political, military and economic performances, such as reclaiming farmland, building water conservancy and implementing the system of selling salt and iron by officials, it has played a positive role in social and economic recovery and economic rectification. ?
