As I was a primary school student, we had been told that we need to use putonghua to conmunicate with our friends. However, most of our classmates are come from local rural area, so if our teacher said, please speak putonghua, we just speak it in the class. Because if we speak putonghua with our friends, it is really weird. Just like, British people would not speak Chinese with their friends even they are in china. As well as, Chinese people would not apeak English with their friends even they are in England. As we all know that there are one dialect die in every ten mimutes in the world. That is a bad news that only english or potonghua live in this world. We call for a multicultral world and a colorful world. Can you emagine that there are only human being left in this world. that is impossible. Our human being can not live in this planet with their own. So just the same with language, dialects should be tolerate in public places as they want to. first of all, tolerate dialects in publlic places can protect our cultural spirits. A language is a cultrue, and also a nation's spirits. It contains a kind of people's mind set and their survival wisdom that we should protect and learn it. Second, protect dialects can make our own language more colorful. Putonghua is a vivid language that it always elited the nice part of other dialects and that make it more intersted and colorful. When we speak it we feel the splendid of our history. When other people learn Putonghua, it will spread our culture and make them feel that chinese diversity cultrue. third, if we ban people speak dialects in public places, some less-educated people can not communicate, because they only speak dialects. To sum up, dialects is a treasure of human being. It should be aloud to speak in public and hand up by generation to generation. Most of all, for some near extinction dialects, government should help and encourage their to inheritation and preservation.Holp we have a vivid colorful world.
