II． Cultural Information
In our daily life, we often need to ask others for permission before doing something. It is good manners to do so. At the same time, asking people for permission before you do something will help you avoid being embarrassed（尴尬）. In other words, if you do something without being told to, others may be angry with you or won't trust you in future.
