Some of them are true but most of them are out of date, incorrect or even false. China is different from many of your previous experiences and may shock you in many ways. This country is changing and progressing every day. Yet it is still a developing country. After the economic reform, most of the developments concentrate in major cities and remote areas are still very backward.
China is a very populated nation and people have to cope with the crowded environment.
Foreign visitors may not get use to the mentality of the people and sometimes become frustrated with the situation, which they never experienced before. Basically Chinese are reserve, peaceful and nice. They are very polite too but in their own way.
