Yunfeng Stone Carving is one of the representative works of Wei stele calligraphy, and its status has always been commented upon. Bao Shichen of the Qing Dynasty said: "There are many side characters in the northern stele. The characters of "Zheng Wengong Stele" are unique, and the seal script style, rhyme and grass style are complete. ... Zhenwenyuan is also a rare treasure" ("Yizhou Shuangji") ·Li Xia Bi Tan"). When Kang Youwei commented on the stone carvings of the Northern Dynasties, he called the Yunfeng stone carvings the pole track of the round pen and listed them among the best works ("Guangyi Zhou Shuangji"). Ye Changchi praised the engravings of "The Upper and Lower Steles of Zheng Wengong" and "On the Book of Classics and Poems", "The upper part carries the seal script, transforming the wild fields in the north, and advancing civilization like a blue road. His strong writing power can control rhinoceros, fight dragons and snakes" , and being able to navigate the void is all about divine luck" ("Yu Shi"). The Yunfeng stone carvings are not only numerous and concentrated, but also available in both large and small fonts. They are as famous as the inscriptions on the Longmen statues, the epitaphs of Mangshan, and the cliffs of the Four Mountains of Zoucheng. They are also appreciated by people for their rich and unique artistic style. Among Yunfeng's stone carvings, the one with the greatest influence and wide spread is "Zheng Wengong's Lower Stele".

The Japanese calligraphy circle has a special liking for "Zheng Wengong's Monument".

The emergence of cliff-carved scriptures in the Northern Dynasties is closely connected with the rise and fall of Buddhism at that time. During the two hundred years of the Northern Dynasties, there were frequent wars, dynasty changes, displacement and chaos, and there was no peace in the world. People yearn for stability and pray for the god from outside to save all sentient beings, while Cihang Pudu gives illusory hope and comfort to people in distress. Under the initiative of the ruling class, Buddhism flourished. The dissemination of Buddhist scriptures and the elaboration of Buddhist doctrines usually rely on scriptures handwritten by scripture writers. The reason for the concentration of sutras carved on cliffs in central and southern Shandong is that the focus of the two exterminations of Buddhism in the Northern Dynasties was in the west. Central and southern Shandong was the hometown of Confucius and Mencius and the stronghold of Confucianism. Buddhism was not as prosperous as in the west of the Central Plains, so the extermination of Buddhism was also slow. ?
