Lishan, adjacent to Huaqing Pool, is one of the must-visit scenic spots for group tours. The mountains are lush with trees. They have been tourist attractions and summer resorts since ancient times. In addition to the natural scenery, the "beacon tower" of the beacon fire drama princes and "Bingjiao Pavilion" of the Xi'an Incident are also here. It is interesting to listen to the tour guide to explain these two periods of history.
