Dali is situated in the southwest of Yunnan China. According to Chinese literature, Dali Ancient City was a gateway to the Silk Road in Southwest China, and also serves as a seat of government and a major military barracks for Yunnan Province in the ancient time. It enjoyed magnificent scale, with a wall length of 6km, a height of 7.5m and a thickness of 6m. There were 4 city gates facing west, east, north and south, upon which sat a gate tower. 4 further towers were also placed at the 4 comers of the city wall.
