Nearly every city has its own Children's Palace, with Pyongyang having the largest. After classes in the morning, selected (gifted) students spend the afternoon at the palatial Children's Palace to practice their art or other special skills. Children choose their area of specialisation in cooperation with teachers once they're old enough to attend (around 11) and continue with that skill every day until they graduate or they complete the area of study. Areas include: ballet, rhythmic dance, gymnastics, computer programming, singing, musical instruments, chess, volleyball, basketball, embroidery and calligraphy.
