During his campaigns to the south, Shi Huangdi commences construction on the Lingqu Canal, which is used heavily for supplying and reinforcing troops during secondary campaigns. Shi Lu was assigned by Emperor Shi Huangdi to build a canal for grain transport. The project was completed in 214 BCE, which is known as the Lingqu Canal today. It has directly secured the South China with military significance. The Canal has been in service for over 2000 years as the major water transport route between Lingnan (today’s Guangdong and Guangxi) and Central China till completion of the Yuehan Railway and Xianggui Railway in modern times. Many have mistaken this for the Grand Canal.
