What is the charging standard of China Beijing Poly Auction Company?

I've experienced it myself. I heard what they said online for free. As a result, I went in person and charged a membership fee of 500 thousand. What a high threshold! Moreover, it does not collect collections from outside. He also said that my collection was not good and I didn't even accept the money. It is also said that they do not collect collections from outside, unless members want local government departments to go through the legal procedures for the formal source of collections, and then they can find local branches or agents to collect relevant auction procedures! After the transaction, the commission is about 15% of the transaction price, and the auction will charge 3% of the reserve price and 1% of the insurance premium! Alas, I didn't know I was here, so I made a trip for nothing. The fare, travel expenses and room and board are all 18 thousand! It is better to go directly to the local institutions to save trouble! Now this society is very realistic. Nothing for nothing.
