Introduction to Taihe Palace: Taihe Palace is built on a steep slope, located in the Taihe Valley in the west of Qianshan Shasha Gang, adjacent to Taihe Gate. The famous natural attractions of Taihe Palace are: (1) Taihe Ancient Pine: outside the gate of Taihe Palace, it is 11 meters high and 2.2 meters around the trunk. It has a history of 300 years and has long been recorded in history. (2) Two Half Stones: Located in the Nanwangou of Taihe Palace, there is a huge stone, 6 meters high and 3 meters long. For some reason, a large 1-meter-wide crack opened in the stone and the top and bottom were the same width, and a piece of stone grew out of the crack. An ash tree is a wonder. (3) Key Stone: Located in the southwest of Taihe Palace, the stone is several feet high and looks like a lock. Therefore, the three words "Key Stone" are engraved on it, which has been recorded in history.
