Congradulations. Your kid is very talented in speech. Is he/she trained by school or you hire other tutor ? Can you share how old is your child and which is he/she studying in ?
80 or above have cert? really? so my son is lucky.
Last year my son also join putonghua speech contest. his score is under 75, but in fact all his classmates and friends in the same occasion score under 75. All are very disappointed.
On that day, some boys are really funny. A boy wear an extra large trouser. He always push his trousers up when giving the speech.
