石头屏风后面就是北山从高空盘绕而下的深壑，极其宏伟险峻，石头屏风的左右两侧，都有小石桥能够分别到达那里。
屏后则北山中空盘壑，极其宏峻，屏之左右，皆有小石梁以分达之。
Behind the stone screen is the deep gap that spirals down from the high sky on the North Mountain, it is extremely majestic and steep, little stone bridges on both  sides of the stone screen can respectively reach there.
