These people are Filipino students. They have painted their faces because they are celebrating Sinulog, a famous Filipino holiday in August.
For Sinulog, people do a special kind of dance. There are drums, and people take two steps forward and then one step backward.
The point of the dance is to celebrate Saint Nio, an important person to Filipino Catholics.
The Philippines is famous for having a lot of Catholics, but it didn't used to.
Even before the Philippines became Catholic, though, people did the Sinulog dance. The meaning has changed, but the dance is the same. Today, people think the dance is important for this reason.
