What is the physical difference b/w Chinese & Japanese Women?

for me they look sort of the same 

when you want a taller wife or girlfriend you go with either chinese or south korean as most japanese are  shorter.

most chinese have long slender bodies which is what i usually whant in  a girl.

Are you all anti japanese or something? There are differences but I like them both the same ^.^

there are no difference

I really can't guess any difference between most of Chinese and Japanese people I meet. Most of times the only indicator of ethnicity I got is their clothes or the way they talk.
Are native Japanese and Chinese people capable to identify each other as Caucasian people?
I am from Europe, and we are all classified as caucasians within Europe.
In most cases a Spanish, a French and an Italian could never identify themselves as foreigners if they cannot speak, same thing for a Swedish,a Danish and a German, but a Swedish and an Italian in most of cases can tell the "differences"
which are the main traits to identify the differences between these two ethnic groups?

Japanese women have circled legs but Chinese don't.

Chinese women have good figure and taller.
