2. It is determined by the name canonized by the previous dynasty. This happens more often. For example, the Qin Dynasty was originally the state of Qin entrusted by the Zhou Dynasty; the Han Dynasty was named the King of Han because the founding monarch Liu Bang was named the King of Han by Xiang Yu; the Sui and Tang dynasties were also named after the titles of the founding monarchs.
3. According to the hometown or place of prosperity of the founding monarch. For example, in the Song Dynasty, the founding monarch Zhao Kuangyin made his fortune in Songzhou, so the country was named Song.
4. The founding monarch determines himself. This situation often occurs in ethnic minority regimes. Generally, Han dynasties in the Central Plains will follow the ancient system when choosing country names and choose from country names that have existed in ancient times. Ethnic minority regimes often do not have this kind of history, so their names are more arbitrary. For example, Liao means "iron" in the Khitan language; Jin means "the beginning of all things" in Chinese because Wanyan Aguda, the founder of the Jin Dynasty, believed that gold was eternal and hoped that his dynasty would last forever; Yuan means "the beginning of all things" in Chinese. meaning.
