Do you still speak dialects?

From my own growing experience, I live in Lanzhou, where there are many immigrants and few people speak dialects, because it is easy to understand each other. My father's side is mostly from the northeast, and my mother's side is mostly from Shanxi, so in order to facilitate communication, I only speak Mandarin at home. Based on this background, I can only speak Mandarin before I leave home to study. Later, I spoke English very well in Britain. There are more friends in the Northeast, and with the influence of grandparents, the Northeast dialect is at the level of my mother tongue. I can fool many people with fluent Beijing dialect, and it is no problem to chat with Tianjin dialect. The gradual disappearance of dialects must have a lot to do with the floating population. For example, my family won't give me an environment to learn and practice dialects at all. Mandarin communication is the most efficient for the whole family. In my opinion, speaking dialects, like speaking Mandarin and speaking English, is the most efficient language under certain circumstances. If you are surrounded by Northeasters, chatting in Northeastern dialect is definitely the most effective way of communication. If there is a most efficient dialect communication environment, then dialects will certainly not die out.
