wang kim » kang kim, wang ke, yong kim
kim tong » kim song, kim dong, kim jong
tong hui » wang hui

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((zhang yan) OR (wang yan))) OR (dong jung)) yet ((a wei) OR (ha wei)) wang kim tong hui ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((zhang yan) or (wang yan))) or (dong jung)) yet ((a wei) OR (ha wei)) wang kim tong hui ;*".
