This sentence is a famous saying by Zhai Hongshen. It talks about the importance of relationships. He has the same meaning as this saying: great achievements pass through the throat, and the ups and downs of a glass of wine are settled. The essence is that in the process of being a person and a business, the kind of people you deal with can determine your structure. As a human being, if you interact with successful people and make friends, you will gradually become a successful person, and you will have the realm and structure of a successful person. If you can be friends with heroes, you will also have the vision and mind of a hero. (For example, Cao Cao and Liu Bei cooked wine and discussed heroes); great achievements are all in a glass of wine.

The same goes for running a business.
