Perhaps you should try some spelling variations:
zhang yan » zhang fan, zhang jian, wang yan
dong ping » dong sin, dong bin, dong jung
lang yan » wang yan, wang yang, yang yang
wei yang » wei wang, wei yang's, wei shang
pei yang » hui yang, pei yun, yi yang
kim tong » kim song, kim dong, kim jong
tong hui » wang hui
ye a » yet a, e a, me a

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