Introduction to Dongshan Purple Air: Dongshan Purple Air is located two miles east of the city. The mountain is not high but beautiful, not connected to other mountains. It has towering ancient trees, lingering vines, and verdant green. In the past, there was a square at the foot of the mountain with the four words "Purple Qi coming from the east" written on it. There was a clear spring in the middle of the mountain and a pavilion on the spring. The winding path goes around the mountain; at the top, it is a flat land with an ancient temple built in the middle, commonly known as Dongyue Temple. The pavilion in front of the scene is very late at night, and it can be said that you feel relaxed and happy when you climb up to the pavilion and face the wind.
