这是在比较民族，种族文化，是大话题。当我还是个孩子的时候，广场上有露天电影。为了不买票，我们会带双筒望远镜前往附近的楼上。我觉得有人现在正在这样做。 这个世界上有各种各样的东西，做事的标准也不同。在我学习工程学之前，老师告诉我们，应该知道，通讯系统所要求的错误率不应超过10 ^（ -  2） -  10 ^（ -  6），大多数，机械制造业生产，误差标准偏差小于10 ^（ -  2）。生物发育虽然不那么精确，但其误差范围小于5％。在人类社会的政治领域，文化，传统领域存在很多不稳定因素，要面对广大群众，对大多数人的心理反应，其变化，误差范围更大。 在民主社会中，如果超过63％的人投票支持某事，那么这个数字已经非常高了。

This is to Compare nation, ethnic culture, big topics. When I was a child, there were open-air movies in the square. In order not to buy tickets, we would take binoculars and went  to the nearby upstairs. I think someone's doing this right now. There are all kinds of things in this world, and the standards for doing things well are also different. Before when I studied engineering, the teacher told us that we should learn, communication system, and the error rate it requires should not exceed 10^(-2)—-10^(-6), Most, machinery manufacturing industry production, error standard deviation is less than 10^(-2). While Biological development, not that precise, its error range is less than 5%. In the political field of human society, cultural, tradition areas, there are a lot of unstable factors, that is, facing the broad massive general public, the psychological responses for majority people, its changes, the error range is even greater. In a democratic society, if more than 63% of the people vote for something, it is already a very high number.
