Introduction to Sanqianbaikan: It is not recorded in the literature when the Sanqianbaikan was first built. It was named because there used to be 3,800 stone steps from the foot of the ridge to the top. After reconstruction during the Republic of China, it now has more than 5,500 levels. In history, Xin Qiji, Wen Tianxiang, Marco Polo, Xu Xiake and other historical celebrities left their footprints here, which can be described as a beautiful scenery and a gathering of people.
