"Native kids English teacher (Black or White) 18,000 rmb"
Also at the bottom of this ad it states:
"you can apply if you are black with good teaching experience and a valid visa"
but then:
"BLACK teachers get 14,000rmb" (>_<)
The folks at the the Cambridge Kids English Centre have taken this ad down, but the cached page of it can still be seen here in Yahoo.
