Perhaps you should try some spelling variations:
dong ping » dong sin, dong bin, dong jung
lang yan » wang yan, wang yang, zhang yan
yang kim » yong kim, kang kim, hyung kim
kim tong » kim song, kim dong, kim jong
tong hui » wang hui
ma wei » ha wei, mr wei
a wei » a weit, ha wei, a web

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: ((lang yan) OR (dong ping)) yet ((a wei) OR (ma wei)) yang kim tong hui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) or (dong ping)) yet ((a wei) OR (ma wei)) yang kim tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) or (dong ping)) yet ((a wei) OR (ma wei)) yang kim tong hui ;*.
