My name is Nam. It was my birthday last Sunday. I invited some of my classmates to the party. They gave me presents like comic books, robots and a teddy bear. We ate cakes, sweets, fruit and ice cream. We drank fruit juice. We sang English and Vietnamese songs. We danced, too. Phong played the guitar and Linda played the piano. The party ended at 7 p.m. We enjoyed it very much.
Question: What did Phong do at the party?
