BBC News on TV, radio and online often brings you stories from across the world. Today we can hear “Life in China”. Have you got a story about life in China today? If you do, please put your stories here.

Wu Peng, Anhui	I am a 14-year-old boy from a poor village in Anhui Province. Like many other left-behind children in China, I live with my grandparents now. My parents went to work in Shanghai several years ago. They call me twice a month to ask about my study. I really miss my parents and I hope I can go to school in Shanghai. I think every child needs parents’ love and care.
Cindy, Shenzhen	I like traveling and I have traveled a lot around China. During the trip, I often find that a number of Chinese often break the rules in public. For example, when I traveled in Hong Kong this year, I saw a kid eating noodles on the underground, which was against the rules. However, the kid’s mother didn’t think she did wrong. Can you believe it? Let’s improve our public manners.
Mike, Shanghai	These days, we’re asked to “clear our plates” when having our meals and say no to wasting. Some of us used to order more than what we could eat. That was a big waste of food. Now we need to finish the food we order. We should also stop wasting in some other ways. For example, we should turn off the lights when we leave the classroom.
