In Miao culture, wine is a very important drink, representing friendship, enthusiasm and trust. So when Miao people propose a toast to you, they will hold the glass high and then pour the wine into your mouth along the glass wall. This process is called "mountain running water", which means that wine flows into your mouth like a mountain stream.
In the process of toasting, if you accidentally touch the hands of Miao people, it shows that you have accepted their respect, and it also shows that you can drink and have a high appreciation of wine. Therefore, it is not only a manifestation of hospitality, but also a test and challenge for the Miao people to hit you in the mountains and rivers, which requires you to have a certain amount of alcohol and drinking skills.
It should be noted that although it is a traditional custom for Miao people to run in the mountains, they should respect the wishes of others at all times and pay attention to moderate drinking, not excessive drinking.
