Small Rainbow Bridge, spanning across the middle section of the brook which flows in front of the Zhuge Liang Memorial Hall, is the only passage through which Zhuge Liang entered into and exited from his residency. It also stretches across the middle section of Three Visit Hall and Self-plowing Field. Luo Guanzhong vividly recorded the anecdote taking place when Liu Bei met Huang Chengyan (Liu’s father-in-law) over the bridge during his second visit to Longzhong against blizzard.
