Introduction to "Bili Li Wan Ren": On the large stone wall on the east side of Sankong Resort, there are four big characters "Bili Li Wan Ren". Each character is about seven feet high and more than four feet wide. The font is simple and vigorous, and the dead pen is exquisite. . It is said to have been written by Zou Yuanbiao, a Fengzheng official and a member of the Ministry of Civil Affairs, during the Wanli period of the Ming Dynasty (1573-1619). There is a poem engraved on the stone wall below. After hundreds of years of wind and rain erosion, the handwriting of the poem is now indistinguishable. Some people also believe that this is the work of Mi Fu, a great calligrapher of the Song Dynasty.
