Murong Xi
In spring 405, Murong Xi, with Emperor Fu with him, attacked Goguryeo's major city Liaodong (遼東, in modern Liaoyang, Liaoning), and had almost captured it. However, he ordered his soldiers to flatten the wall so that he could enter with Empress Fu on an imperial wagon. The delay allowed the Goguryeo forces to refortify the city, and he was unable to capture it.
