Introduction to Rangquan: The Rangquan in "The Drunkard Pavilion" is located on the south bank of the glass marsh near the Drunkard Pavilion in Langya Mountain. A square pool is built with stones around the spring. The square pool is three feet square and is no more than a foot deep. Remain. There is an inscription with the word "Rangquan" above the square pool.
Rang Spring never dries up, and the water temperature remains at 17-18°C all year round. It is "as sweet as wine and as clear as glass," and is also known as the "Glass Spring."
