the definitions of and the division between xiwen and chuanqi, one may conclude that they belong to the same tizhi juzhong (dramatic genre defined in terms of textual form). In the Yuan period, xiwen was also called nanxi southern drama) or nanqu xiwen; as a tizhi juzhong, it was the countrpart of beiju (northern drama), which was also known as beiqu zaju. Hence the well-known opposites of xiwen/zaju and nanxi/beiju. Xiwen was first developed in the Song period; by the early Ming it had been greatly influenced by beiju and the literati's culture, thus paving the way for its transformation into chuanqi. The term chuanqi means "extraordinary matters that are worthy of transmitting" or "transmitting the extraordinary matters". It had been used as a general generic category covering the Tang short stories, the Song-Jin zhugongdiao, the Song-Yuan xiwen , and the Jin-Yuan zaju. In the Ming critic Lu Tiancheng's Qupin (The Evaluation of Qu), for the first time the term was adopted to denote the longer xiqu by the Ming playwrights. Lu used the Kundshan tune as the criteria to differentiate the new and the old chuanqi. The so-call "new chuanqi" differed from xiwen in its musical modes and meters. Viewed from the development of traditional Chinese drama, chuanqi did not emerge as a distinctive tizhi juzhong until the Ming times. To put it in another way, nanxi was gradually transformed into chuanqi by way of the converging influences of beiju, the literati's culture, and the Kundshan tune. From the perspective of qiangdiao juzhong (dramatic genre defined in terms of musical mode), since chuanqi was influenced by the Kundshan tune, it should also be regarded as a type of Kun opera. For two reasons, the category of chuanqi does not cover the Yiyang opera, the Haiyan opera, and the Yuyao opera. First, by the Wanli period of the Ming dynasty, the Haiyan tune had vanished. Second, very few of the works which used the Yiyang or the Yuyao tunes were passed down to the later generations. Among these works, the tizhi juzhong of those which could be sung was xiwen; but the generic norms of xiwen had not only stopped to evolve but also were gradually destroyed, leading to the demise of the qupaiti and its replacement by the banqiangti. Accordingly, they cannot be viewed as a form of chuanqi. In fact, Ming-Qing shcolars never regarded the Yiyang and the Yuyao as the proper tunes for the "new chuanqi" that had developed rigorous generic rules after the Wanli period. As to the exact time of the formation of chuanqi, I have discussed it in a previous article, "Cong kunqiang shuodao kunju" (From the Kun tune to the Kun opera). My views may be briefly summarized as follows. If we follow the new/old division of chuanqi made by Lu Tiancheng in his Qupin, then the old chuanqi refers to those texts which were sung with the Kunshan tune since the early Ming , while the new chuanqi refers to those which were sung with the Kunshan shuimo tune invented by Wei Liangfu. Since those "old chuanqi" texts included in Lu's Qupin were all dated before 1559, and the year also saw Wei Liangfu establishing himself as the master of the Kunqu school, we may conclude that the "new chuanqi" texts included in the Qupin were produced after 1559. In other words, the years around 1561 could be the time when the new chuanqi made its first appearance. When the Huanshaji (The Story of Washing Yarn) finally came out and was widely circulated, more and more people came to adopt the Kunshan tune and thus made it the most popular music of the time. The one hundred and sixty-five "new chuanqi" plays included in the Qupin testify to the supreme position that the new chuanqi had attained in the Jiajing and Longqing periods. To sum up, in the history of traditional Chinese drama, what Lu called "new chuanqi" was the new tizhi juzhong that came after xiwen. Furthermore, from the perpective of qiangdiao juzhong, since chuaniqi was sung with the Kunshan shuimo tune, it should also be included in the great family of the Kun opera.
