Introduction to the Wall of Quotations from Cultural Revolution Sites: The Wall of Quotations from Cultural Revolution Sites is located in Sijia. It was built in 1974 and faces east to west, with eight facades lined up. The Quotation Wall is a brick-concrete herringbone beam building with a two-slope roof, a whitewashed wall with large blue tiles, a setback door slope decorated with patterns, and a retractable door covered with iron sheets. After its completion, it has been used as the business place of Kongcheng Supply and Marketing Cooperative. At that time, only in this place could Kongcheng people "invite" leaders' portraits and badges to post and wear at home. On the wall of the building facing the street, there are eight quotations from Chairman Mao and four slogans including "Long Live the Great Communist Party of China" written in red paint. Chairman Mao's handwriting "Serve the People" is cast in cement and has high preservation value and far-reaching historical significance.
