Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
parent a » parent _, parent ͳ
jiu tong » jiu cong, jiao tong, xin tong
liu yong » liu yang, liu yirong, jim yong
yang yi » yang di, yang xi, yang jui
brent z » brent b, brent d, brent a
yi hua » li hua, ya hua, yi hui

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

• Performing a fuzzy search may retrieve terms with similar spellings: yang yang yi hua ((parent a) or (brent z)) ((jiu tong) OR (liu yong)) shui ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang yang yi hua ((parent a) OR (brent z)) ((jiu tong) OR (liu yong)) shui ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang yi hua ((parent a) or (brent z)) ((jiu tong) OR (liu yong)) shui ;".
• Adding a wildcard symbol may retrieve word variants: yang yang yi hua ((parent a) or (brent z)) ((jiu tong) OR (liu yong)) shui ;*.
