Revolutionary model operas are a unique art form that appeared during the "Cultural Revolution" movement. Their plots are based on stories of laboring people struggling and fighting for happiness. The operas were made into films and TV shows for promotion nationwide. Stills of the characters and scenes were printed on posters, stamps and craftworks. It was a mass commercial campaign even though people didn't understand it in those terms at the time. As the dominant art form in people's lives for about 10 years, the revolutionary model operas and their impact on society are worthy of careful analysis from a pop culture perspective.
