Guo Jing becomes an active member in defending the city of Xiangyang from Mongol invaders. After successfully establishing a base of operations in the city, Guo Jing and Huang Rong work closely with Xiangyang's military forces and their "wulin" allies to defend the city. The couple have three children; elder daughter Guo Fu and the twins Guo Xiang (girl) and Guo Polu (boy). Guo Xiang's name is inspired by the "Xiang" in "Xiangyang" while "Polu" means "defeat and drive away barbarians" (the "barbarians" refer to the Mongol invaders in this context).
