Introduction to the used book trading market: Since 1986, every Sunday, used book trading activities will be held in the square in front of Dacheng Hall. In the 1990s, the Confucian Temple Secondhand Book Market gradually became the most famous secondhand book market in Shanghai. During the renovation of the Confucian Temple, a "Confucian Temple Books and Periodicals Trading Market" was specially designated in the northeast of the Confucian Temple and east of the Zunjing Pavilion, making the book trade more prosperous. In addition, antique buildings consistent with the architectural style of the Confucian Temple were built along the three walls of Laodaoqian Street, Menghua Street and Xuegong Street to serve as shops selling antiques, calligraphy and paintings, etc.
