People in China

We all know that there are about 1.2 billion people in China - that's about a fifth of the population of the earth. So when we go visiting the famous tourist places in China, surely there would be a lot of people there. Still it amazed me that there were a lot of people in such places as the Great Wall, the Forbidden City, Tiananmen Square etc., and the very long queue of visitors to go into the Mao Mausoleum. On the Great Wall at Ba Da Ling one can hardly walk without bumping into someone.
