The vendor doesn't care about what's crude or not; he's selling antiques, so all he wants is for things to be sold. As for the status of the buyers, he doesn't really concern himself with that.
The stalls at Dashilar are all movable. Generally, vendors here don't stay in one place for long.
Rental spaces here are calculated by the week. Vendors rent a stall for a week, and once the period ends and they've sold most of their items, they move to other places to sell and collect some vintage trinkets.
This young stall owner isn't a local either; he's a trader who collects items from antique market hubs monthly, picking up things that catch his eye. Sometimes he finds older items, buys them, and resells them at the Antique Street.
The black pottery jar in Huo Sining's hand was something he got from an old farmer's house in the countryside for ten yuan a while ago.
