In the Qing Dynasty, “Flower Drama” (Huabu) is opposed to “Elegant Drama” (Yabu) “Elegant Drama’ means Kunqu. The numerous others musical styles dramas were put into the category of “Flower Drama,” also under the name of “Luantan,” including the future Pekin Opera, Beiguan drama in Taiwan, and many provincial dramas in China. This essay compare three “Luantan” dramas collections to observe the changes in the dramaturgy owing to the differences of the spectators, theatres, and the time. The first one is “Dramas Collection in Mongol’s Che Princely Mansion of the Qing Dynasty” (Ching Mongu Chewanfu Cang Chuben) which includes many “Luantan styles” dramas collected in the end of 18th century before the Pekin Opera was formally recognized to be the official drama. The second is “A Collection of Peking Opera Texts” (Xikao) that contains plenty of texts of Pekin Opera played mostly in Shanghai during 1913-1924. The third consists of some Beiguan drama texts, which have collected since 1960s by Luodong Fulanshe, a Beiguan community theatre. Beiguan dram was probably performed in the beginning of the 19th century. Beiguan music and drama have been very popular all over Taiwan. By analysis these texts form three collections, we can get some conclusions: 1.As the primary form of Pekin Opera, “Dramas Collection in Mongol’s Che Princely Mansion of the Qing Dynasty” have owned the basic and complete plots in its texts. 2.To be performed in some commercial treasures, the texts of Xikao have been simplified, and some surrealistic scenes removed. 3.Beiguan drama not only inherits plots from the primary Luantan drama, and continues to include some surrealistic scenes, but has also developed its own characteristics, like more erotica dialogues and some “clichés” (stereotypes) in general use.
