Ming-Qing qü writers usually compared The Peony Pavilion with The Story of the Western Wing (hereafter The Western Wing) at the same level as the masterpieces. This comparison matters because The Western Wing represents the best Yuan play and inherits from the northern qü tradition. It symbolizes that The Peony Pavilion was viewed as the "new classic" of chuanqi plays in the new era of Ming dynasty. In the eyes of Ming-Qing literati, Yuan qü was treated as the model of playwriting and thus considered having the highest status in comparison with other dramatic styles, so the closer to Yuan qü's shape and spirit, the closer to the height of the classics. The connection between The Peony Pavilion and The West Wing implies that the Ming-Qing literati provided their opinions and understanding of the two plays from the angle of the Yuan drama and the northern qü. This article will combine the playwright's text with some critics' opinions in order to observe how Tang Xianzu's contemporaries regarded his writing strategy as a way of absorption and transformation from the Yuan drama, and thus provide an alternative view to interpret The Peony Pavilion as a classic of Ming drama.
