What's a ""folded"" theater, please? Does anyone know?

General "folding" is the essence of a play, generally omit the beginning and end, directly into the climax, is the most exciting part of a play, this part of the most attractive to the audience, but also the most able to show the actor's performance skills. The "folds" that my brother is referring to must be the "folds" of Huang Ye's song, right? This is a commemoration of the first anniversary of the death of his idol, Leslie Cheung, and Mao Hui specially created: Leslie Cheung's "Farewell My Concubine" was a sensation for a while, to the point that he himself was caught up in the drama, and ultimately ended up committing suicide. And the "folding" that "Farewell My Concubine" sublimation, which "if everyone is a folding play, in the play to release the joy of sadness and happiness; if the earth to lose the colorful mask, is not also someone to go to stay to regret? If everyone is a piece of drama, it is only one part of the whole play, usually not the beginning and the end, it is more of a kind of incomplete charm, so that there are not so many hateful and unsatisfactory," the protagonist of the false society's distaste and helplessness is expressed to the fullest extent. The lyrics reflect the ambivalence of people's desire for truth, goodness, beauty and perfect life and their difficulty in resisting worldly vanity.
