He Lou is a tall, fierce-looking man who appears cold on the outside but warm on the inside. He takes a leadership role, warning the group to be ready to escape and instructing them to move backward on the subway. He is skeptical of Li Fangwan's trustworthiness and notices changes in the subway's lighting, suspecting abnormal causes. He resists the hypnotic effect of the phonograph music, at least initially, and leads the group in running from danger. His eyes clear momentarily when Lu Yanli bumps into him, suggesting he may have been under the music's influence.
