Zhuge Liang sat upon the walls of the cities  far outnumbered by the Wei army which advanced toward him. Zhuge  sat upon the walls and played his instrument without fault, and thus tricked Sima Yi into thinking that the Shu had troops hidden in the surrounding area for an ambush. Zhuge Liang was able to quickly flee the area as the Wei retreated.
