During the production of her operas and ballets in the 1970s, Madame Mao describes the wound to the actresses, actors, artists and the nation. Madame Mao says, Our heroines must be covered with wounds. Blood-dripping wounds. Wounds that have been torn, punctured or broken by weapons like shovels, whips, glass, wooden sticks, bullets or explosions. Study the wounds, pay attention to the degree of the burn, the layers of the infected tissue. The color transitions in the flesh. And the shapes that remind you of a worm-infested body.
