Information about life under the Qing was transmitted abroad by various means. Both Korea and Japan shared a common written language with China. Official ambassadors from the Korean Chosŏn dynasty regularly visited Beijing, but exchanges with Tokugawa Japan were limited to private Chinese merchants visiting Nagasaki. Europeans had less opportunity to gain information, although a few Jesuits living in China did undertake the study of its language, history and customs. Their efforts were supplemented by foreign accounts of Canton or by reports from those few embassies that made the journey to the capital.
