Why do Hasidic men have curls?

Hasidic men have curls, known as "payot," as a religious expression of their adherence to Jewish law, specifically the Torah's commandment not to cut the hair on the sides of their heads. This practice is a way to demonstrate their faith and commitment to their cultural identity. The length and style of the curls can vary among different Hasidic groups, but they all serve to signify their devotion and connection to tradition.
