First of all, as the client, you should contact an auction house (you can check it from the investment promotion section of the local newspaper or online). After receiving your request, the other party will ask a painting and calligraphy expert to identify the authenticity of the entrusted goods. If it is genuine or valuable imitation, the auction company will accept your entrustment and determine a suitable starting price and reserve price.
After that, the auction company will issue an auction announcement or use its own network to find potential bidders, so as to maximize the benefits.
Then there will be an auction to auction your consignment.
In this process, the auction company will charge you a certain commission, and if the auction is successful, it will also charge you a certain percentage of the turnover according to the situation.
Order, if you only have one consignment and the value is not big, the auction company is likely to reject your request or wait until a certain amount is accumulated before auctioning.
I hope my answer can help you.
