"Seres" meant either China proper – in which case the Greeks achieved the first direct contact between China and a European society, some time around 200 BCE – or the peoples of the Tarim. In any case, a city known to the Chinese as Dayuan, which was mentioned by scholars from the Han dynasty (1st century BCE to 2nd century CE), was almost certainly Alexandria Eschate. The prefix "da" meant "Great", while the suffix "Yuan" was the Chinese rendition of Ionians.
