Introduction to painting and calligraphy: In front of the main hall of Longshan Temple, there are three pairs of painted works of door gods. Among them, the door gods of the front door are "Weituo" and "Jialan", the two major protectors of Buddhism, and the door gods of the side doors on both sides are the "Four Heavenly Kings". In addition to large-scale paintings, many exquisite works were painted on the center of the main hall, mostly with flowers, birds, characters, and historical stories as themes. In the main hall, there are also inscriptions by many famous people, such as Yu Youren, Huang Guoshu, Xie Guansheng, Huang Chaoqin, Ma Shouhua, etc., which add a lot of humanistic and artistic color to Longshan Temple.
