Knowledge link: This is the word "fugue" written by Lin Yu 1987, a famous calligrapher in Yongjia, Wenzhou. There are two meanings: one is to praise Yandang Mountain as a fairyland on earth; The other is that appreciating the natural beauty needs a process of integration, so I hope every tourist can keep calm, put aside the secular world, enjoy the scenery with a relaxed mood, forget things and reach the highest level of tourism.
