     Hotlines have become common in China. Some radio broadcasting stations use hotlines to encourage

the listeners to take part in the talk show. Are you interested in hotline?

      That's a good idea. Yet, the fact is, some people do nothing but break the whole program. Some people

know little about the topic under discussion. Sometimes they even do not know what the host 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 ignorance. Then 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 for fun. They just want to let the listeners hear them. They

do not care about what the topic is, whether they themselves are interested in or how silly they appear to be.

      I am really bored by those people. It is necessary for the radio station to improve the hotline program.

In my opinion, if a caller does not know what is going on, the operator should not let the caller take part in it.

Some young children phone the hotline in order to take part in games.

     Some radio or TV stations hold the hotline in order to get more money from the children. So if your

phone fee goes up quickly suddenly, maybe your son or daughter often phone hotline. There is another

hotline. Everyone likes it very much. It is the hotline for our life, such as Mayor Hotline in your city.
