Introduction to Tianzhong and Tiangu: There are two huge red rocks next to Ganlu Temple. The left one is like a huge "bell", while the right one is like a huge "drum" that is unique in the world. They are masterpieces of nature's uncanny craftsmanship. It can be said that there are "bells in the sky and drums in the sky", so Ganlu Temple has the slang saying "the drum on the right and the bell on the left, the temple (wonderful) is in it".
