Introduction to Xi'er Bridge: This Xi'er Bridge is surrounded by three clear water fish ponds. The mountain springs in the ponds flow all year round and are clear and never dry up. According to legend, it was built by a scholar from Quzhou in the Song Dynasty when he was relegated to seclusion. As time goes by, the small bridge made of bamboo and wood has been replaced, but the legend about ear cleaning has been passed down for a long time. According to legend, Xu You was a wise man in the era of Yao and Shun. Because of his noble moral character and extraordinary intelligence, he was highly respected by the tribe. Yao wanted to pass the throne to him, but he sternly refused and fled to Jishan in Dengfeng to live in seclusion. Yao sent people to find him again and wanted him to serve as the governor of Jiuzhou. He went to the Yingshui River to wash his ears, saying that he did not want to hear such words. Xu You therefore became the originator of later hermits, a model who was indifferent to fame and fortune or valued justice over profit.
