(If the auction is so easy to make a fortune, the masters of Panjiayuan antique market and ground stalls in Beijing will not pay booth fees, and they will suffer in cold and hot weather all day. Antique shops have long been closed, and stall owners and antique shop owners can save rent to participate in the auction, so the auction can only make some lucky people rich, so everyone will participate carefully. If it is so easy to get rich, people all over the country will do antique business. ) There are many units dealing in antiques now, so be sure to ask clearly before joining, and then join when you feel fit. Once the auction is over, you should be able to accept the reality of the cost loss, otherwise it will be too late to regret it, because no unit can guarantee that you will make a deal. If there is security, you will meet a liar. Secondly, the safest way to trade a collection is to set up a stall for sale. Although lucky in the storm, it costs 100 yuan per day. When you encounter a favorite cash transaction, the relative risk is relatively small. When you meet an irregular auction unit, you have to pay one or two thousand yuan. If we don't close the deal, the loss will be too great. Secondly, if the family is in difficulty, try not to participate in the auction.
