Whenever I am out, there are lots of people staring at me, saying "Laowai!"

I hate this too much! Can't they be more polite and civilized??

That's true. Many Chinese people like to stare at foreigners.

I hate that too.

I never stare at foreigners.

I get this so much , i live in a very rural area and people even stop on there bikes to look it gets crazy at times but thats just how it is , i like to stare back or ask them some random question in chinese.

0.0? What for ? I am Chinese hmm and hardly do that, but I can understand . If a Chinese person go to your country , one of your compatriots never seen a Chinese person in reality before, he or she might stare at that poor Chinese man for a long time and says:"Wow i saw an Asian, it looks like a freak 0.0" within their hearts...

Through what you experienced , try to learn the reason why you experience that. The window from China to outside world had been close for centuries, although it have been open for recent decades, It still takes time for the unlucky and poor Chinese people to adapt the new world ,the new things, the new faces.
And by the way , i have been stared at by many of them in my childhood also.Coz they thought i had been too tall to be a kid. But,right now,I am just about 6feet,The memories like that used to make me painful.now i think i should have taken it as a joke thing."They wish me to be a dwarf".
Take care man, my motherland is dangerous for people who don't know it deeply:)
