What should I do if I want to believe in Buddhism and learn from it, but my relatives laugh at me?

Caring about other people's jokes is also a manifestation of my persistence. You don't have to pay too much attention to it. You can learn and recite Buddha naturally, always correct yourself with the words and teachings of Buddha, and gradually become a reasonable practitioner. In this way, the changes to the people around you will increase little by little, not only changing their views, but also serving as an example for Buddhist disciples to make good friends with them.

If they laugh at you and are suspected of making a living, you should have compassion, compassion, skill and convenience, and don't let them make a living.

Let go of yourself, as Master Yin Guang said, I am the only ordinary person, and others are Buddhas and Bodhisattvas. Treating them with such a respectful and equal attitude is naturally effective!
