It is a very remarkable fact that, in the register of Chinese cities and counties for the year a.d. 5, there should appear a city and county with the most ancient Chinese name for Rome. The Chinese, then as now, did not give foreign names to their cities. In that list, with its over 1,500 cities, there are only two other Chinese places with foreign names. We know that both those localities were populated by immigrants who came from those places outside China. It follows that people from the Roman Empire must have emigrated to China and founded this city.
