Early life and education
Wang was born in Wuhan in Hubei Province. Although he wanted to become an actor after performing Thunderstorm in school, his father wanted him to do sports while his mother wanted him to find a stable job. As a result, he worked as a book porter at Xinhua Bookstore after high school. During his free time, he took on side jobs such as attending activities organized by TV stations, taking model-training courses, and shooting commercials. In 2002, during the shooting of a commercial, the director suggested Wang attend an acting academy. Wang resigned from his job and moved to Shanghai to take courses on acting at the Shanghai Theatre Academy in 2002. The next year, he applied for the Beijing Film Academy and the Central Academy of Drama. Wang received offers from both academies, and chose to attend the latter.
