They are always ragging the teacher about his accent .
他们总是取笑这位老师的口音。
When I was in university , the ragging was far worse .
大学上我的时候，恶作剧比这糟糕多了。
And for all the people ragging on the rude child well I assume the adults know how to turn the lock to prevent unwanted sex education which they failed to do .
