Introduction to the stone carvings of "The First Country in the World": According to legend, during the Three Kingdoms period, Liu Bei came to Dongwu to marry his wife. Sun Quan accompanied Liu Bei to watch the river scenery after the banquet. Liu Bei saw that Beigu Mountain stood majestically on the riverside, and the river went eastward, stretching as far as the eye can see and majestic. , couldn't help but praise: "Beigu Mountain is really the best country in the world!" Later in the Southern and Northern Dynasties, when Emperor Wu of Liang climbed Beigu Mountain, he saw the spectacular scenery of Beigu Mountain and wrote "The Best Country in the World" with great enthusiasm. The six characters were left on the mountain, but unfortunately they can no longer be found. In the Southern Song Dynasty, Wu Zhi, the governor of Runzhou (Zhenjiang) and a famous calligrapher, rewrote these six characters. During the Kangxi period of the Qing Dynasty, Cheng Kangzhuang, the general judge of Zhenjiang Prefecture, copied the stone. From then on, Beigu Mountain was rightly known as "the best country in the world".
