Сурва is a festival that happens in Bulgaria. It's a special celebration where people wear costumes and masks, dance around and sing songs. They also make noise with bells and drums to scare away any bad luck or evil spirits that might be around.
During сурва, people usually go from house to house and perform their dances and songs for the homeowners. In return, the homeowners give them treats and small gifts. It's like trick-or-treating, but with more dancing and costumes!
This festival goes back a long time and is part of Bulgarian tradition. It's a fun and exciting way for the community to come together and celebrate their history and culture.
