石头城
Sun Quan (182-252), ruler of the Wu Kingdom, had what is now called Stone City built on a hill overlooking the Yangtze. It was used for naval training by General Zhou Yu (175-210). On a political visit to the area, the prime minister of the Shu Kingdom, Zhuge Liang (181-234) described the Qingliangshan Hill and Stone City area as "Zhongshan curling like a dragon and the Stone City crouching like a tiger".
