Legend of Condor Heroes (2008)

When their husbands are killed by the Song Army, two pregnant women escape to foreign lands and both give birth to boys who are very different from each other. Guo Jing (Hu Ge) is a strong but dull-headed young man who grows up on the Mongolian prairie. Yang Kang (Justin Yuan) is a smart and skilled you man who is raised as the son of Wanyan Hong Lie (Guo Liang), a successor of the Jin Empire. The worlds of these two men collide when their respective martial arts masters make a secret pact, while their lives are further complicated by the love of two women, Huan Rong (Ariel Lin) and Mu Nian Ci (Liu Shi Shi).
