Foshan in Guangdong and Yangliuqing in Tianjin, Yangjiabu in Weifang in Shandong and Taohuawu in Suzhou were once called the four woodblock New Year pictures in China. Foshan has been listed as one of the four famous towns in China in Song Dynasty, with developed economy and culture, and the paper industry and printing and dyeing industry have also developed greatly, which has already met certain conditions. During the Song and Yuan Dynasties, the custom of carving and painting door gods became popular in Guangzhou and Foshan. In the early days, this door god was hand-painted directly on the door panel, and later it was carved on other boards to make woodcut New Year pictures, which were sold in the market for people to post.
