Introduction to the Alchemy Furnace: The Alchemy Furnace is located at Xiaozi Peak in the northwest of South Peak. According to legend, it was the place where Taishang Laojun refined golden elixirs. There is an old temple building, but it is small in scale. There is an iron alchemy furnace in front of the temple. The stone-carved alchemy furnace in front of the present temple is three feet in diameter and more than ten feet high, with exquisite carving and simple style.
