Jenny and Sarah are practising singing a Vietnamese folk song to take part in a singing contest only for foreign students who are studying in schools in Ho Chi Minh City. Their song is Hoa thom buom luon. It has a beautiful melody, but they find it challenging because the lyrics are difficult for them to pronounce. With the help of Miss Thanh, their Vietnamese tutor, their performance is improving significantly. Besides singing, they also have to practise a traditional dance in order to impress the judges and the audience. Although the dance is not as difficult as the song, they still rehearse very hard. With a lot of efforts, both girls hope they will have a great performance and win the contest.

1. Who can compete in the singing contest?
