Please help promote the current trend of chasing silver, chasing platinum, and the next copper ancient coin, with square holes and round bodies, symbolizing "Heaven is round, Earth is square." It carries calligraphy, measures, and the concept of existence and non-existence, reflecting the thousand-year trade exchanges and cultural融合. Collecting it not only preserves a tragic history and top-tier minting art but also guards a nation's memory that can never be forgotten. Its cultural and market value endures and becomes more precious over time.
