Introduction to the upper stream of Youquan Stone: The mountain is surrounded by water, and the water runs through the mountain. This is a unique feature of Yaoshan Mountain. In the scenic area, there are crisscrossing ravines, deep rock ravines, and mountain streams that flow continuously all year round. Clear springs flow out from the cracks in the rocks, with strands of strands and the music of the piano. The stream divides and joins in the rocky valley, swaying, sometimes like an unruly wild horse, rushing thousands of miles, roaring.
