Eating a banquet in the countryside, will you be found if you mix in?

It will be found that all the people who come to eat the banquet are relatives of the host family and a villager. In addition, the countryside is not big. Even if not everyone knows the relatives of the host family, several people can recognize them together, so it is impossible to pretend to be relatives, let alone pretend to be villagers. Villagers can recognize at a glance whether they are mixed in to eat and drink.
