Eastern Henan, such as Shangqiu Kaifeng, should respect the elders first, and the younger generation can't drink until the elders have finished drinking. Mutual respect among peers. The glass should be deep and stuffy, and there should be no wine left. In western Henan, the opposite is true. For example, in Luoyang, drinking is optional. You can't drink empty cups for people, you should drink more wine. Most other areas are similar to the eastern region.
