Although Hellas is an ancient name of Greece in the English dictionary, it is the name of Greece in Greek. In the city-state era, Heiles was the self-proclaimed name of all Greeks, which was different from "barbarians". Similar to China, during the Spring and Autumn Period and the Warring States Period, although the Central Plains region had its own country name, it also claimed to belong to "Huaxia". Greece and Greece are not the full English names for the Greek Republic. The word Hellas comes from Pilars, the ancestor of Greek mythology, and Helen, the son of deucalion. The Chinese word "Greece" is directly translated from Greek, not from English.
