Introduction to Baibao Lake: It is 65 meters long from east to west, 24 meters wide from north to south, and 1-4 meters deep. It is an underground lake formed by karst. The water of the lake is crystal clear, and the stalactites on both sides are reflected in the lake in various shapes. The two stone pillars next to the stone wall by the lake are more than 20 meters high and are hugged by three people. They are round on the outside and hollow on the inside. They make a clanging sound when knocked lightly. On both sides of the lake, there are clusters of "silver mushrooms" and stone flowers, like natural bonsai. There is also something called "hair-sucking water ball" in Baibao Lake, which is rare in caves at home and abroad.
