       Are you sorry for not traveling during the National Day? If you stay at home at that time, I think you

  are very lucky. Why? Because there are too many people everywhere. In many places of interest in

  China, it's too crowded to do anything.

       It was too crowded on the Great Wall on National Day in 2010. You even (甚至) couldn't take

   photos for you or your friends. All what we could see were people. It was reported that there were

  about twenty people per meter on the Great Wall. My friends told me they could see nothing but many

  people on the Great Wall. "We couldn't walk if the people in front of us didn't walk," he said. He

  showed us a photo on the Great Wall. In the photo, we hardly found him out, there were too many

  people.

       So some people give the advice that we should not have the gold week any more. But other people

  say no about this advice. What's your idea of it? Are you sorry now for not traveling during the gold

  week? I love staying at home more than traveling next National Day.
