Except Taishan Mountain, Culai Mountain and Wenshang Buffalo Mountain, these eight peaks are all in Zoucheng City. Among them, the four peaks of Jian, Tie, Ge and Gang are relatively concentrated within 30 Li, also known as the "four mountains" and the "cliff of the four ancient mountains".

The cliff carvings in Geshan and Yishan belong to the Northern Zhou Dynasty. Although they have been eroded by wind and rain for more than 400 years, the handwriting is still very clear. Cliff stone carvings are based on heaven and earth, with mountains as materials, displayed in natural space and integrated with natural scenery, which is the unity of humanistic calligraphy and natural environment, artistic beauty and natural beauty. But I saw huge boulders standing quietly, engraved with the essence of Buddhist scriptures, like a mysterious stone scattered on the Buddhist scriptures in Shan Ye. With its unique momentum, the engraved scriptures are consistent with the quiet and lush natural environment, and with natural fonts and characters, it gives people a natural, extraordinary forest and a sense of vastness. Its artistic style of calligraphy is magnificent and changeable, with the change of official script into the main style, the combination of seal script, regular script and calligraphy, which is grand in scale and lofty in artistic conception. It is known as "the originator of Chinese characters and the master of book list". Cliff stone carving is a combination of natural landscape, religious culture and calligraphy art.

It truly reflects the times style of the evolution of official script, which is natural, harmonious and natural, and has amazing artistic beauty.
