Abstract: The tendency of stage performance, unlike that of play writing, to a large extent, depends on the audience's preferences. Chinese traditional operas focused on the stage highlights bear a longer vitality. Among the stage performances of Xi Xiang Ji (Romance of the Western Chamber) in Ming and Qing Dynasties, excerpts of lyrical parts and boisterous parts were most popular. Re-creation of the opera stage takes the role of acting as the core and sets aside enough space for the show by refining the traditional opera formula. Furthermore, some marginal episodes are gradually separated from the whole opera and become separate excerpts.

Key words: Chinese traditional opera, formula, stage, Xi Xiang Ji (Romance of the Western Chamber)
