Ranwu to Bomi is known as the "Glacier Township", which has many glaciers, and the largest are "Laigu Glacier", "Midui Glacier" and "Renlongba Glacier". Unlike the "Laigu Glacier" and "Midui Glacier" that have been developed as tourist attractions, the "Renlongba Glacier" has not been developed yet, and it still maintains its original state, hidden in deep mountains and little known to outsiders.
