Meanwhile,each competitor must pay attention that you had better speak fluently without notes.What's more,your performance should take no more than five minutes.
Aside from a slew of performances and competition, attendees will have an opportunity to win a prize from the lucky draw. You are welcome to join us and actively participate in this competition.
