What did Qin Shihuang do to develop Lingnan?

Qin Shihuang also recruited exiles, slaves and businessmen to settle in Guilin, Hunan and Nanhai counties, which basically unified Lingnan. Later, Qin Ershi recruited 65,438+05,000 unmarried women to Lingnan. These women later married soldiers and locals, built homes and started businesses, and never returned to the north. Qin also moved a large number of prisoners and mainland people here for garrison farming.
