personal observations:
They are very polite, sometimes too much. But you really don't know what they are thinking about me as a chinese, paticularly around the end of 80s, and early 90s (that was the time period I had contact with them) china was not as developed as now.
But they like to drive american cars, and told me that in Japan, american cars were expensive. They also like to play golf, saying in Japan it was expensive to play golf too, compared with in FL.
