A house was built in the village, and now it has been built. Is it necessary to set wine for the whole village?

That depends on the customs there! Some places serve wine, saying it's warm wine. You call it partnership wine. If there is, put wine. If not, it is not necessary. If you do, I'm afraid people will gossip! It's good to invite you to dinner, but I'm afraid people will say that you have more money than you can spend! Also, if you invite people to dinner, they have to pay the bill with gifts and money, in case someone doesn't like it! If there is such a custom in the village, it is ok to have dinner and wine, and people all have banquets. You are incomplete and inappropriate!
