I am surprised by your feedback as we have heard for years that Chinese students cheat all the time.

Also, I wouldn't know what to make of all the search hits I might read, especially since presumably there's cultural context I don't understand.
If you work with engineers from China, I suspect you'll notice many favorable qualities. Maybe including an implicit "No Jerks policy" (in American tech company terms).
You'll also notice that they're all distinct individuals (in American terms), and though it might be human to prejudge groups/labels of others, that's not fair to individuals, and we strive to be better than that.
