Introduction to the Zhentan Sacred Stone: The Zhentan Sacred Stone is also known as the "Lake Stone". It is blue-gray in color and full of beauty. The stone is 5.55 meters high and weighs more than 5 tons. It is steep and straight, standing majestically, like a Guanyin Bodhisattva guarding the Wulong Pond. There are more than 10 scattered lake stones scattered next to it, forming a group of "boys worshiping Guanyin" picture. It is a rare natural art treasure.
