Do you mean the dialect in your hometown when you describe the same language? If so, contact them directly. After all, he is a fellow villager, and there are still many topics to talk about. Don't be afraid of rejection. Maybe introversion makes you feel inferior, or it makes you introverted in some ways. Either way, introverted personality is overwhelmed in society, and people can't all be smooth sailing. Contact them, they accept you, you are the first step out of introversion, if you don't accept you, you will be rejected, which is not an experience. You must experience all kinds of failures in life.

Be brave, get close to them, pay attention to your way of speaking, and don't associate with unhealthy young people.
