Introduction to Hanging Wall Road: Guoliang Village is surrounded by mountains on three sides and faces cliffs on one side, which makes the villagers here live in isolation for generations. In the autumn of 1971, in order to actively respond to Chairman Mao's call of "man can conquer nature" and to get rid of the fate of generations of poverty and to prevent the descendants behind them from walking the steep ladder, at the suggestion of Shen Mingxin, secretary of the village party branch, villagers Shen Xinfu and Wang Huaitang , Shen Fugui used ropes to measure height and distance, and used native methods to draw, and started the construction of Guoliang Wall Highway.
