We are the Henan side of the drinking etiquette, the drinking field veterans please teach.

In the eastern part of Henan, such as Shangqiu and Kaifeng, the first thing to do is to honor the elders, and the elders have to wait for the elders to drink before they can finish. The other side is to honor each other. The glass of wine should be emotionally deep and boring, there can be no leftover wine. In the western part of Henan, it's the other way around. For example, in Luoyang, drinking is casual and there should be no empty cups. Most of the other regions are similar to the situation in the east.
