The nature of a `饭局` varies greatly depending on the context.
Business `饭局`: These are often formal and can be high-pressure. They are used to build rapport with clients, negotiate with partners, or seek favors from officials. Heavy drinking, particularly of `白酒 (báijiǔ)`, and elaborate toasting rituals are common. The conversation may only turn to business toward the end of the meal, or not at all, with the understanding that the strengthened relationship will facilitate future business.
Social `饭局`: These are gatherings among friends, family, or old classmates (`老同学`). While more relaxed, they still serve a purpose: celebrating an event (birthday, graduation, promotion), catching up, or simply reinforcing social bonds. Even in a casual setting, there are still unspoken rules about hosting and being a good guest.
Purposeful `饭局`: This is a `饭局` organized with a very specific goal in mind, such as asking for a significant favor, introducing two people who could benefit from knowing each other, or resolving a conflict. The meal provides a neutral, friendly environment to broach a sensitive topic.
