What's the difference between a chinese and a japanese person?

The Japanese person will learn/remember to duck each time they pass through the doorway. The Chinese will find another way to enter in the future.

Out of three major species of human thes e are from mangolian kind. There is no difference between any mankind on this earth. Chinese and japanese both are hard working, sincere and trust worthy people.

ummm one is from china and one is from japan. i dont really know what other kind of answer you are expecting. that's like asking 'what's the difference between an egyptian and a russian person?' there are lots of differences biologically as well as culturally i guess. i usually can tell the difference in looks between chinese and japanese but not always.
