What are the procedures for antique auction?

If it's Ming and Qing porcelain with ID cards and porcelain, it's unsuccessful to collect catalog fees, just to earn catalog fees. You can call China Poly or China Guardian to ask, they don't charge catalog fees. Since the country has not fully officially opened cultural relics, porcelain after the Yuan Dynasty cannot be auctioned publicly. Some small auction companies auction works of art, not to mention antiques, even if the auction is perfunctory, no foreigners dare to buy it. Cultural relics cannot leave the country because there is no national document to lift the ban. Those so-called transactions are all their own goods, and placards are all their own childcare. Please don't sponsor for the purpose of earning catalog fees. Suggestion: If it is the Ming and Qing Dynasties, you can go to China Poly or China Guardian; If it's after the Yuan Dynasty, I can't shoot it now, soon, and so on. Poly, Guardian and other regular auction companies can shoot it, which means that the cultural relics are fully open.
