Tiankeng geosyncline
Text/Li Zheye
What a surprise! There is a huge pit between the mountains.
The cliff is like a ghost axe, and the earth suddenly sinks because of magic.
Looking down at the pale rocks and green trees, I can see white clouds and blue sky.
The towering peaks are connected with the distant peaks, and the lower ones are embedded in the ground to sew up the maze.
The scenery of the sinkhole is so strange that I suspect that I am in a fairyland.
I want to visit the prehistoric history of another world in the center of the earth.
