There seems to be a new set of four treasures on sale, but it seems that it needs to be ordered one day in advance. There is a family in Dongjiao, which seems to have been handed down from generation to generation, but I don't know much about that. I heard that the set of four treasures is around 3-4. It's not cheap, so I've never eaten it. It seems that there is a new set of squid baked noodles. Go to Kaifeng and have a new look.
