What are the good points,and the bad points,about studying in another country

Studing in another country has good and bad points.The good points are that you can learn their language more quickly and understand their culture easily.What you learn English in China lasts five years equals what you did abroad only one year.It greatly shortens the time which you need to master English.
the bad points are that you have to change your way of thinking to fit into foreign society.You should scratch from nothing without any support from your family background.You have to face a lot of temptations such as drug,prositution and mental problem.You should be well prepared physically and mentally to face this problem by your self rather than frenquently get support from your family in China.
