My classmates and I talked about the traditional culture, folk art and folk customs of our country. They said I was a local and had a strong taste. What should I do?

You don't have to tell them that they are not interested in the traditional culture of our country. This is the lack of education and the shortcoming of their ideological culture. Young people with your hobby are rare now. Do yourself well, pursue what you love, pass on our traditional culture, folk art and folk customs, and strive to carry them forward.
