Note: The extremely cautious foreigner should be on the road, as the culture of driving here is fundamentally different from the culture of driving any other country (one can say, the traffic rules are not respected at all): double solid lines, as well as turning signs in China are simply ignored. Despite the most dangerous driving style, terrible fatal accidents here are extremely rare. For a foreign student in China there is always a work in progress, you just need to be the owner of a light skin. Such a lucky person, and especially with golden hair and blue eyes, a model career is ensured. Well, if in addition to his appearance a foreigner can boast of a good level of English, he has good chances to become a private tutor or teacher at school. The main thing is not to get caught by the police: work on a study visa is strictly prohibited.
