The poem "Hanging the Xuan Tomb" says: "Fine grass occupies the tomb field, and mud has already recorded money. Pedestrians don't want to see flowers, let alone too mysterious. " In Guangfu annals of the Republic of China, Qingzhou was the secretariat of Yutai in the Eastern Jin Dynasty, and he lived in seclusion in the mountains in his later years. According to legend, Yutai is mysterious and tolerant. On the day of grave-sweeping, thousands of swallows came to pile up soil for their graves. Therefore, the mysterious tomb refers to both the tomb of Yu Taixuan and the tomb of swallows (mysterious birds) buried with soil, hence the name. Since ancient times, Xuanmu Mountain has had the reputation of "Xuanmu potential, three dragons and three phoenixes, the best in the world". Xuanmu Mountain is located in the south of Guangfu Town, connected with Dengwei Mountain, facing Taihu Lake in the south, Midui Mountain in the east and Changqi Mountain in the west. The three mountains meander together to form a natural dustpan bay with excellent terrain. Mr. Jin made this place a virtual swallow dock in Tianlong's novels. It can be seen that there is a poem behind every martial arts and place name written by Jin Yong, and it really deserves its reputation!
