Sūn Quán 孫權 (182–252), founder and first emperor (Dàdì 大帝, r. 222–252) of the Three-Kingdoms state of Wú 吳, with its capital at Jiànyè 建業 (later renamed Jiànkāng 建康). He is relevant to the early-Chinese Buddhist record principally as the imperial patron under whom the Sogdian-Vietnamese missionary Kāng Sēnghuì 康僧會 arrived at Jiànyè in Chìwū 赤烏 10 (247 CE) and persuaded the court of the truth of Buddhism by producing a Buddha-relic; Sūn Quán thereupon erected the Jiànchūsì 建初寺, the first Buddhist monastery in the lower-Yangzi region. He was also the patron of the earlier translator Zhī Qiān, who served at the Wú court as bóshì 博士 from c. 222 CE.
