Xia Weitao: public information is limited, and the only known work by this author is Chuzhou Luantan. Chuzhou is an old name for the area around present-day Lishui, Zhejiang, while luantan is a traditional opera vocal style popular in southwestern Zhejiang, closely tied to local folk customs, dialects, and rural life. The title Chuzhou Luantan suggests a compilation and introduction to this local opera, possibly covering its origins, vocal characteristics, repertoire, and transmission. Since only this one work is held in the database, it is difficult to judge the author's overall writing style or scholarly orientation, or to confirm their background and research focus. Based on the available information, Xia Weitao's writing appears to center on local opera and traditional culture, and readers may regard the book as an introductory work on the Chuzhou Luantan genre.
