Hundreds of sinkholes are the result of geological factors and reduced groundwater, which have led to an increase in the incidence of ground subsidence in the area in recent years, resulting in numerous sinkholes in the area.

Almost all sinkholes extend downward in a spiral shape and seem to be bottomless.

The tiankeng varies in size, ranging from a few meters to a dozen meters or tens of meters in diameter, making people look very small standing around them.

There are still some timid people who dare not get close. There seems to be a deep terror there, and the deep breath from the earth emanates from the sinkhole.
