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

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 (li cong))) OR (kim song)) 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 (li cong))) or (kim song)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang gan guan hua ((dan yang) or (tan yang)) ((((li rong) OR (li cong))) or (kim song)) hai ;*.
