How should an auctioneer grasp the atmosphere of the venue?

One side of the auctioneer is the client, and the other side is the bidder (or buyer). How can an auctioneer satisfy them all? How to make each auction have a different impact? How to mobilize the atmosphere of the auction venue on the basis of adhering to the principle of "openness, fairness and justice"? These operations are necessary for an auctioneer. It is not a problem for every auctioneer to satisfy both sides and realize the principle of "three fairness", but it is a bit difficult to make the atmosphere of the venue lively. Generally, the atmosphere at auction venues is serious, tense and dull. Just like a court session, the auctioneer seems to be a judge, standing on the auction platform with a serious expression, giving people a feeling of being above others, which often causes a sense of tension and depression to bidders. Once the bidder is in this bad state, it will directly affect the transaction price of the auction target, resulting in the transaction price being either too high or too low, which is not expected by the auction house. Therefore, an excellent auctioneer should mobilize the atmosphere of the auction and let the bidders be in the best state. Only in this way can they have a reasonable transaction price for the auction target.
