Perhaps you should try some spelling variations:
keong ghi » hong ghi
wang gan » wang yan, wang ban, wang dan
tan yang » dan yang, tan ying, tan yong
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai
hua tan » hua ban, huan t'an
li hua » li hui, lu hua

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang gan li hua tan yang jin ((keong ghi) OR (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang gan li hua tan yang jin ((keong ghi) OR (hong hai)) ;*.
