Introduction to stone archways: There were originally 8 stone archways in Qingyan Ancient Town, but now only three remain, namely the "Zhao Caizhang Centenary Archway" outside the north gate and the "Zhou Wang's Wife Liu" in Dingguangmen. "Jiexiao Square" and "Zhao Lilun Centenary Square" in the south gate are both oriented north-south, 9.5 meters high and 9 meters wide, in the style of four pillars, three rooms and four roofs.
