Introduction to the cliff carvings: The small door in the northeast corner of the temple turns west and is the famous "Calligraphy Alley". There are two huge stones facing each other, leaving a gap about one meter wide and four to five meters long in the middle. Nearly 700 regular script characters are engraved on the two walls of the hutong. They were written by eminent monks from Hangzhou, Wenzhou, Chang'an and other places across the country during the Hongwu period of the Ming Dynasty. The poems left behind by a Dharma gathering held in Zangsi can be called a wonder.
