Perhaps you should try some spelling variations:
wang luhang » wang liang, wang lihong, wang yuhan
duong hai » dang hai, duong van, hong hai
tan puay » tan hua
tan chia » tuan china, than china, can china
dan yang » daun yang, wang yang, yang yang
tan yang » tan ying, tan yong, tao yang
tuan vu » thanh vu, tuan hua

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 luhang ((((tan puay) OR (tan chia))) OR (tuan vu)) ((dan yang) OR (tan yang)) le duong hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang luhang ((((tan puay) or (tan chia))) or (tuan vu)) ((dan yang) or (tan yang)) le duong hai ;*.
