Introduction to Qizi Island and Chen Lin's Tomb: According to historical records, Chen Lin, one of the "Seven Sons of Jian'an", was a native of Dongshagou, Sheyang Prefecture (today's Dongshagou Village, Dazong Lake). The famous "Wen on Discussing Cao Xie" was written by Chen Lin when she was serving as Yuan Shao's staff. After Chen Lin died, Cao Cao ordered him to be buried by the Dazong Lake. Qizi Island is built today to commemorate it.
