Introduction to the "Tiankai Wenyun" stone carving: "Tiankai Wenyun" is the largest cliff stone carving in Xiangxi Prefecture. It is located between the cliffs on the north bank of the Youshui River in the old dock of Youshui (commonly known as the middle dock) in Baojing County. The four characters "Tiankai Wenyun" are arranged horizontally from right to left in Yan style and Yin script, thick and powerful; on the left are nine characters of Mengxia Monthly in the 17th year of Guangxu's reign, in regular script and Yin script. This stone carving was left by the Baojing people in the early summer of 1891 and represents the good wishes of the Baojing people.
