Meng Liang Ladder (or Staircase) is at the entrance to Qutang Gorge, on the southern bank of the river and to the east of the Whitewashed Wall. It is a Z-shaped series of holes chiseled into the rock face, each hole measuring 33 cm deep, 24 cm wide and 21 cm high and with a 1-meter interval between the holes. They are arranged half way up the mountain and out of the reach of climbers. Meng Liang is a favorite of Yang Jiye, a famous general in the Song Dynasty (960-1279) who fought against babarian invaders.
