★You may need others’ help in many situations such as asking the way, asking for advice or seeking help. However, people are very indifferent to each other in cities in china. People are not willing to offer help to others. Once a young man sent an old woman who stumbled by herself to the hospital, unexpectedly the old woman’s son who is a cop asked the young man to compensate for the high medical expenses. This is very common in China. Therefore you’d better ask the familiar for help if you need. You could become the familiar even with several conversations. The familiar could be all called “朋友”（friend）in China, while“兄弟”（buddy）is a kind of usage to try to get close in relations among friends.
