The Chinese movie that won the Cannes Film Festival’s highest honor finally has been approved for general viewing in China after minor editing.The Chinese government banned “Farewell to My Concubine” in July, apparently because of displeasure over its theme of homosexuality. The film opened Wednesday in select Beijing theaters and is supposed to be shown in all theaters on Saturday, theater employees said Thursday. The movie chronicles the life of two Beijing opera students who become stars together, performing the opera from which the movie takes its name. One star is a female impersonator who plays a concubine who falls in love with the king. No reason was given for the decision to allow the reopening.
