It should be Zhang Yimou and NOT the other way around. 
Yimou is the surname, not the given name.
Apparently people here are taking the credits from the IMDb without realizing that they switch the names around 
for Asians.
Asians refer to themselves last name first and first name last, however their first name is STILL their first name 
and we do not live in the east.
This is no different from "Bond, James Bond" 
It's James Bond, not Bond James, likewise its Akira Kurosawa, not Kurosawa Akira.
