Introduction to Yingjia Hall: Legend has it that when King Zhongyou came to Dawang Cave, he was hungry and thirsty. It was the nectar dripping from this stalactite that looked like a palace lantern that brought a touch of coolness to the king, so it was named "Yingjia Hall". There are cave karst wonders such as "Eight Immortals Crossing the Sea", "Brewhouse", Ostrich, "Thousand Finger Forest", "Acacia Forest", "Jiuquan" and so on.
