Introduction to wind erosion columns: In addition, some wind-eroded residual hills have particularly developed vertical joints in their sand and mud layers. After repeated cutting and wind erosion of many heavy rains, the soft sand, soil and stones were swept away, and the original massive rocks were swept away. Stone pillars cut into strips become wind-eroded pillars. These wind-eroded pillars are carved by strong winds like knives and axes into shapes that resemble objects, humans, birds and beasts. They are various and lifelike.
