Perhaps you should try some spelling variations:
wang kang » wang yang, wang liang, wang yan
gang hari » dang hai
tuan hua » tuan vu, yuan hui
dan yang » daun yang, wang yang, yang yang
tan yang » tan ying, tan yong, tao yang
tan hua » wang hua, tan chia
xi gang » ii gang, i gang, li gang

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 kang ((((tan hua) OR (tan puay))) OR (tuan hua)) ((dan yang) OR (tan yang)) xi gang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang kang ((((tan hua) or (tan puay))) or (tuan hua)) ((dan yang) OR (tan yang)) xi gang hari ;~".
• Adding a wildcard symbol may retrieve word variants: wang kang ((((tan hua) or (tan puay))) or (tuan hua)) ((dan yang) OR (tan yang)) xi gang hari ;*.
