I major in history, especially Chinese culture, and I am a descendant of a clan. Just listen to me. In the Western Han Dynasty, courtiers (excluding eunuchs and low-ranking officials) must call "Your Majesty" in person, and "county official" when talking to acquaintances (this is the biggest difference from other dynasties), and to strangers, especially foreigners. They should be called "Shang" and "Jin Shang". Everyone else is a slave, and they all call "Emperor" directly ("Emperor" means "big, beautiful"). The reason why all ministers in later generations called the emperor "Your Majesty" and "Long Live" is because the monarch's power continued to strengthen and the status of ministers became lower and lower. The power of life and death rested with the emperor, and ministers were no different from slaves.
