Yi He Ming was first carved on the stone wall at the foot of Jiao Shan in Zhenjiang, and it was not recorded until the middle Tang Dynasty. Since the discovery of the remnant stone in Yi He Ming in the Song Dynasty, calligraphers of past dynasties have admired it to the utmost, and there is no conclusion yet, which has become an eternal mystery. In the fifty-second year of Emperor Kangxi of the Qing Dynasty, Chen Pengnian, a Suzhou magistrate living in Zhenjiang, recruited workers to salvage five pieces of ***93-character residual stones. According to experts' research, the original text of Yihe Ming should be about 160 words, and there are still many shortcomings. Since then, the salvage of the residual stones in the novel heming has become a "complex" that haunts the academic circles. After cleaning, rubbings, identification and evaluation, it is found that there are some residual characters such as "Fang", "He", "Hua" and "Zhi" on the 453, 587, 546 and 977 rockfalls salvaged from 1000, which are compared with the inscriptions of "He He He Ming" recorded by predecessors. On August 25, 2009, the boulder suspected of being engraved with "Yi" was partially blasted to reduce the burden, so that the whole stone could be salvaged, which made people wait for it.
Jiao Shan, Zhenjiang is known as the "mountain of calligraphy", and there are many inscriptions written by calligraphers in past dynasties, many of which are treasures. The most famous is the "King of Historic Sites" in Baomoxuan Forest, with the signature "Yang Hua Yizhen, Huang Shang Qiao Shan Zheng Shu". This is a memorial article in memory of cranes. Although the content is not enough, its calligraphy art is indeed valuable.
