Introduction to Kui Ven Tower: Kui Ven Tower is 49 meters high, 10 meters in diameter, and has an octagonal masonry structure. On the wall of the fourth floor, there are three bluestone inscriptions on the Kuiwen Pagoda rebuilt by Wang Gengyan and others. In the bricks on the third to seventh floors, there are the marks of various brick factories at that time. There are stone steps inside the tower that can be spiraled up. There was once a pagoda courtyard under the pagoda, with several houses built in the pagoda courtyard, including Chunyang Tower, Mrs. Huiji Temple, Cangjie Temple, Xizi Furnace, Guanshui Pavilion and other ancillary buildings. By the end of the Qing Dynasty, these ancillary buildings had collapsed one after another, leaving only the Xizi furnace.
