Different area people use different speech, which called the dialects. for this circumstanse, some people reffer to the object attitude. in my opinion, i insist that people shouldn't use the dialects in public places. for one hand, dialects influent the contract of people. we all know that dialects has the strong phnetics and meaning. it is normal that ,people cann't understand the meaning of other people. in the other hand, dialects present the diffiernt culture. people can introduce it in provate time. all in all , we accept the differnce in language but we should conside the development and contrct among people.
