I actually see this first hand so I'll tell you my experience.
At my school, they were passing out flyers to anyone that "looked Chinese, but not Chinese American" as "potential converts".
What they were looking for, hard to say, so I'll just say what I was wearing: nylon black Nike basketball jacket, bright green Adidas shirt, black pants, black backpack, listening to mp3. They walked up to me and in Chinese (this was a school with thousands of Asian Americans), asked, "Do you want to join our club?" and handed me a flyer.
It was a flyer about a bowling party, with the latest internet slang, in Chinese, all free, and at the very bottom, in tiny letters and in English:
"Sponsored by City of XXXXXXX Taiwanese Church"
It was a recruitment party.
Why were they targetting CHINESE but not CHINESE AMERICANS? Here is my theory:
1. Chinese students might be lonely, so they'll want to come more, than the Chinese Americans who grew up in the US.
2. Chinese Americans are most likely already Christian so it is a waste to target that demographic.
3. Chinese students might misread the tiny English letters.
Now if you think this was isolated, don't be fooled. Other people met them too.
