Introduction to Yinfeng Gate: Yinfeng Gate was originally called the East Gate, and its original construction is unknown. It was built with stone during the Chenghua Year of the Ming Dynasty and is one of the relatively well-preserved ancient city gates. From Yinfengmen to Pingqiao, you will see willow silk on both sides of the Wumu River, and the moss path is quiet and winding. When you enter the Dai Temple, you will reach the ancient Feiyang Mountain. The mountain peaks are so tall and graceful that they look like flying phoenixes. The stone platform on the top of the mountain is like a phoenix tripod, facing Guanzi Mountain in the west of the city. The ancients believed that this mountain and this scene condensed the spiritual energy between heaven and earth, so Feiyang Mountain was renamed Feifeng Mountain, and the east gate was renamed Yinfeng Gate.
