Чжан Цянь
The Han dynasty diplomat and explorer Zhang Qian, who visited neighboring Bactria and Sogdiana in 126 BCE, made the first known Chinese report on Parthia. In his accounts Parthia is named "Ānxí" (), a transliteration of "Arsacid", the name of the Parthian dynasty. Zhang Qian clearly identifies Parthia as an advanced urban civilization, whose development he equates to those of Dayuan (in Ferghana) and Daxia (in Bactria).
