Why do people always call me by my first name and add a brother to the last word?

This may be because the last word of your name is more representative, and adding the name "brother" makes it easier for people to remember your name. At the same time, the name "brother" can also express a certain sense of intimacy and respect, which may be one of the reasons why others like to call you that.

However, different people in different regions have different preferences for addressing, so some people like to address others with other addresses. If you don't like being addressed by others, you can express your thoughts to the other party appropriately and let the other party know your feelings, so that the two sides can communicate and communicate better.
