"The Histories" of Herodotus pointed out that the auction can be traced back to the ancient fifth century BC in Babylon. At that time, an auction of marriageable women was held every year. People sent beautiful women to the market, and bidders offered bids to get the girl they wanted. The real commercial auction was created in ancient Rome. The ancient Romans auctioned carpets, palaces, statues and other items. Through various auction mechanisms, the game allows participants to participate in a series of auction activities to understand the principles behind various mechanisms and the applications in real life.
