Perhaps you should try some spelling variations:
yang yao » yang yang, yang yi, yang fan
ying hua » wang hua, ying zhu, dong hua
ming hua » ming hung, wang hua, ming lu
fan hong » tan hong, can hong, fan hongye
hong hai » shang hai, zhong tai, dang hai
yan fan » yang fan, yan clan, yan guan
wang » wing, wan, lang

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 yan) OR (yang yao)) ((ying hua) OR (ming hua)) ren yan fan hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (yang yao)) ((ying hua) OR (ming hua)) ren yan fan hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (yang yao)) ((ying hua) OR (ming hua)) ren yan fan hong hai ;*.
