Perhaps you should try some spelling variations:
wang liang » wang yang
yang yang » wang yang, wang yan
hua rene » hua ren, juan rene
yang can » yang fan, yang dean, yang jin
can hong » tan hong, care hong, wang hong
hong hai » shang hai, zhong tai, dang hai
ka hua » ya hua, ka chuan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (yang yang)) ka hua rene yang can hong hai ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (yang yang)) ka hua rene yang can hong hai ;*.
