Introduction to the Valley Glacier Group: The Sanxi River Valley Glacier Group is another rare mountaintop glacial group discovered in Changle, following the Minjiang River Glacier Group and the Jiangtian Town Qingtianmao Glacier Group. Previously, Professor Han Tonglin conducted continuous inspections in Changle and confirmed that several glaciers below the waterline are the lowest glaciers in the country. They are large in scale, numerous in number, and well-preserved. It is a rare sight at this altitude and can be called a wonder of the world.
