Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
wang wei » zhang wei, wang zhi
ming hua » ying hua, ming hung, ming lu
rene han » rene ten
thi hong » tan hong
hong shu » cong shu, tong shui, wong shiu
yang yi » yang di, yang xi, yang jui
han thi » nhan thi, phan thi, ha thi

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: ((yang yang) OR (yang yi)) ((((wang hua) OR (wang wei))) OR (ming hua)) rene han thi hong shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang yi)) ((((wang hua) or (wang wei))) or (ming hua)) rene han thi hong shu ;*.
