Wu Yong is a thin, cowardly survivor who follows a group and hides behind a restroom door to ambush Lin Chu with a rusty fruit knife. He is easily subdued and faints at the sight of his own blood. He had taken the last intact door in the restroom to set up his shelter, planning to take advantage of the two women. He represents the predatory and weak elements among survivors. He disappears after being knocked out.
