re: Who would win between Rome and Ancient China?

Japanese are complete opposite of the Chinese. One of main Japanese cultural concept is "Iidoko Dori" which means regardless of their origins, accept and digest anything good and produce them as Japanese.

During the Meiji Restoration era(1868-1912), the Japanese carried out modernization by deliberately studying and adapting Western political, military, technological, economic, and social forms. They decided to completely ditch the archaic Chinese system. As a result Japan became a military power but even the Japanese couldn't beat the West. Chinese have no chance.
