Guardian and Poly are the best works of art when they are auctioned in Guangzhou, but people charge appraisal fees and Tulufei fees, which are basically 5% of your quotation. It's called a cut before meeting. It is suggested that you should not be a big head ghost if you are not really sure that there is a market. In addition, making antiques, like Bao Tong in ancient and modern times, has a lot of appraisal fees and storage fees. Even if you make a careless system, as long as you pay the appraisal fee and the exhibition storage fee, others will pay your price.
If there is a real market, it is recommended to cooperate with small and medium-sized auction houses.
