The principle of being a good person and doing things: The outer circle and inner square of copper coins are also endowed with the principle of being a good person and doing things, that is, to be smooth in doing things, but to maintain a square heart. The symbol of folk culture: Copper coins play an important role in ancient Chinese folk life and are regarded as possessing supernatural "divine power", which can successfully complete folk activities and achieve the ultimate goal of folk activities. For example, copper coins used for special purposes such as washing children's money, scattering accounts, and dowry money all have auspicious words and patterns, and are used to celebrate important life events such as childbirth and weddings. The embodiment of philosophical ideas: the circular shape of copper coins represents the principles of equality, inclusiveness, and harmony, while the square shape represents the principles of hierarchy, elasticity, and distance differentiation. This design reflects the ancient people's profound understanding of the universe and life. In summary, ancient Chinese copper coins were not only circulating currency, but also important carriers of culture, philosophy, and folk customs, containing rich cultural connotations.
