Hongkou District plans to develop a zone to showcase the revolutionary and cultural history of the Communist Party of China (CPC). The area, which will cover 2 square kilometers near Sichuan Road N., has 57 historic sites. They include the Memorial Site of the 4th National Congress of the CPC, the League of Leftist Writers Museum, and former homes of renowned writers and intellectuals from early last century. The zone — between Wujin Road in the south and Luxun Park in the north — has the most historic sites, mainly from the 1930s and 1940s, among  downtown areas, according to the district government.
