Southern-Sòng cí-writer of imperial-clan (zōngshì) descent (fl. late twelfth / early thirteenth century, c. 1185–1230), self-styled Xiānyuán jūshì 仙源居士, of Nánfēng 南豐 (Jiāngxī). His zì is not recorded. Held no official rank — described by the Sìkù tíyào as “content with non-advancement, self-pleasing with wine and cí.” His sole surviving work, the Xīxiāng yuèfǔ KR4j0049, in 10 juǎn (around 339 cí in the Quán Sòng cí), is one of the largest single-author cí corpora of the Southern Sòng. The collection has the unique editorial feature — among Sòng single-author collections — of being arranged by season: Chūnjǐng 3 juǎn, Xiàjǐng 1, Qiūjǐng 1, Dōngjǐng 1, Zǒngcí 3, Shíyí 1; this arrangement was made by his contemporary xiānggòng jìnshì Liú Zé 劉澤. Zhào is conventionally placed at the head of the Sòng zōngshì cí tradition (Zhào Yànduān 趙彥端, Zhào Shīshǐ 趙師使, Zhào Yǐfū 趙以夫).
