In China some radio broadcasting stations use hotlines to encourage the listeners to take part in the talk shows.

That's a good idea. Yes, the fact is some people do nothing but break the whole programme.

Some people know little about the topic under the discussion¹. Sometimes they do not even know what the host(主持人)is talking about. So the host has to tell the caller what the show is about. Usually the caller will ask a few questions which express his hope and show his ignorance²(无知). The host has to answer and explain──how silly this is! It wastes a lot of time.

It seems that some people phone the hotlines in fun. They just want to let the listeners hear them. They don't care what the topic is, whether they themselves are interested in the topic or how silly they appear to be.

It's necessary for radio broadcasting stations to improve the hotline programmes. In my opinion, if a caller doesn't know what is going on, the operator³ should not let the caller take part in it.
