We can see them every day，on every street corner，on every construction site （建筑工地） in cities．They work day and night in the terrible working conditions and weather．They build the roads，the theaters，the cinemas，and the supermarkets．They're China'smigrantworkers．

More than 140million workers have left their homes to look for job in cities．They hope to be rich，but they realize they have many problems making money．And one of the problems is the pride and discrimination （歧视） from the people in cities．

When night falls，I can see the sad faces of the migrant workers everywhere．You can see them playing cards along the streets．Many are living far away from where they work．

I can sometimes feel their pain，knowing exactly what it feels like to live so far away from home in a city where I walk a different walk and talk a different talk．

Yes，they dress differently and speak differently．Different habits，but they work hard．The people in cities regard them as outsiders，and most governments refuse to give them medical care and public schooling for their children．

So many things need to be changed．The first is discrimination!They may not make as much money as some people in cities，they may not have everything we have，but they are honest．They are very important and necessary to China's economic development and have become an important force for the change of Chinese society．They're building the new China．So we should help them with our hands．
