The exposure of some weaknesses in China and the victory of garbage everywhere at the World Expo once triggered a big discussion in the Shanghai media. But after discussion, there is no substantial change. Many measures, such as putting up signs that you should walk on the left and stand on the right when taking the elevator, eventually disappeared. Some people attribute this to China's large population, which is indeed a key factor. Others attribute it to the imperfection of some facilities. I went to Japan some time ago. It is said that Tokyo has a large population, and some subway lines are not necessarily crowded than Shanghai, but on the whole, Tokyo has remained quiet and orderly under the premise of a large population. The imperfection of facilities is an excuse for many people. Because we saw too many trash cans around us, but we also threw them away. If you think about it, you may find some reasons for this. First, we in China have no faith. I can't understand how useful such things are, because I don't have any religious beliefs myself. It's just that when you step into the church, the silence and solemnity, the influence of music and painting art, and various baptisms may subtly calm people down, maintain order and cultivate sentiment. What's more, many religions, in this life or in the afterlife, ask their followers to put aside their sins and do good deeds in order to avoid "original sin", which can also make people understand the constraints. The second reason is education. To tell the truth, whether it is family education, school education or social public education in China, the education of etiquette, order and rules is too lacking. Many times, when the child begins to educate, it is covered by our sentence "He is still a child". What's more, you can only have one child now, which is hard to touch. Come to think of it, foreign children are really not so noisy, while most children in China always cry. When you grow up, it is natural to be incorrect or difficult to change. And poverty, I think, is a very important reason.
