Task: Question Generation
Input (English): Passage: The Weilüe and Book of Liang record the arrival in 226 AD of a merchant named Qin Lun (秦論) from the Roman Empire (Daqin) at Jiaozhi (Chinese-controlled northern Vietnam). Wu Miao, the Prefect of Jiaozhi, sent him to the court of Sun Quan (the ruler of Eastern Wu during the Three Kingdoms) in Nanjing, where Sun requested that he provide him with a report on his native country and its people. An expedition was mounted to return the merchant along with ten female and ten male "blackish coloured dwarfs" he had requested as a curiosity, as well as a Chinese officer, Liu Xian of Huiji (in Zhejiang), who died en route. According to the Weilüe and Book of Liang Roman merchants were active in Cambodia and Vietnam, a claim supported by modern archaeological finds of ancient Mediterranean goods in the Southeast Asian countries of Vietnam, Thailand, Malaysia, and Indonesia.Yule mentions that in the early 3rd century AD a ruler of Daqin sent an envoy with gifts to the northern Chinese court of Cao Wei (220–266 AD) that included glassware of various colours. Several years later a Daqin craftsman is mentioned as showing the Chinese how to make "flints into crystal by means of fire", a curiosity to the Chinese.Another embassy from Daqin is recorded as bringing tributary gifts to the Chinese Jin Empire (266–420 AD). This occurred in 284 AD during the reign of Emperor Wu of Jin (r. 266–290 AD), and was recorded in the Book of Jin, as well as the later Wenxian Tongkao. This embassy was presumably sent by the Emperor Carus (r. 282–283 AD), whose brief reign was preoccupied by war with Sasanian Persia.
Output (English): What is the name of the person who Sun requested to provide a report on his native country and its people?
