Perhaps you should try some spelling variations:
wang gan » wang yan, wang ban, wang dan
gan guan » yan guan, quan guan, fan guon
guan hua » tuan hua, gui hua, tan hua
dan yang » daun yang, wang yang, yang yang
tan yang » tan ying, tan yong, tao yang
kim song » kim young
kim eung » kim young
li rong » yi rong, li cong, li song

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 gan guan hua ((dan yang) OR (tan yang)) ((li rong) OR (((kim song) OR (kim eung)))) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang gan guan hua ((dan yang) or (tan yang)) ((li rong) or (((kim song) OR (kim eung)))) hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang gan guan hua ((dan yang) or (tan yang)) ((li rong) or (((kim song) OR (kim eung)))) hai ;*.
