There're many migrant workers in China.Especially in the southeast coastal regions eith high sconomic development level.They are one of the social members.But as for the construct of the city,the migrant workers have done a great contribution.With their hard work,many tall buildings have been built and we have the flat roads to work.Many productions have been took to abroad .They have been really contributing to our economy in a certain degree.

However,apart from their great contribution,they have done something bad to the city's development.We can see so many phenomenons.They often threw away the rubbish everywhere.And speak some dirty words.The development of cities must stress citizens to behave in a cilivized manner,be polit and observe common courtesy.But the migrant workers just do the oppsite.

In my point of view,we can't blame them.Because of the limit of knowledge,they may not do well as us.They can do well on condition that they need others to guide them.So we can't be prejudiced towards them.
