                 BBC World Have Your Say:
     "Life in China" Every day, BBC News on TV, radio and online brings
you stories from across the world. But what we want to hear are the stories
that matter to you.  Have got a story about life in China today? If you do,
please put your stories here.
     I like travaling and I have traveled a lot around China. During the trip, I often
find that a number of Chinese don't have good pulic manners(举止). They always
loudly on the phone and smoke everywhere. The worst is that they often break
the rules in public. For example, when I travled in HongKong in January this year,
I saw a kid eating noodles on the underground , which is against the rules. However,
the kid's mother didn't think he did wrong. Can you believe it? Let's improve our
public manners. (Mike, Shenzhen)
     I am a 14-year-old boy from a poor village in Fuyang , Anhui Province. Like
many other left-behind children (留守儿童) in China, l live with my grandparents
now. my father went to work inn Shanghai several years ago. Last year, my mother
went there to care for him because his health is not as good as before. They tell me
to listen to my grandparents and call me about twice a month to ask about my study.
I really miss my parents ans I hope I can afford to go to school in Shanghai. I think
every child needs parents' love and care. (Wu Peigen, Anhui Province)
