Why should a man and a woman sit separately at the dinner party?

It is an ancient tradition that men and women eat at different tables. Generally, women from feudal families in rural areas in the north did not eat at the table, but they are much better now. Also, when attending weddings, men and women basically sit separately. Women spend a long time drinking and eating together, while women usually take care of their children and don't drink much, so they eat at different tables.
