Perhaps you should try some spelling variations:
jeang yean » jeong yeon
wang dong » wang hong, wang yang, wang jing
wang yong » wang yang, wang hyoung, wang yan
chang min » zhang ming, chang mae, chan ming
yang xi » yang di, yang yi, yang jui
xi test » ai test, i test, ii test
kan min » han min, kian ming, kyaw min

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 dong) OR (wang yong)) yang xi test ((kan min) OR (chang min)) jeang yean ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dong) OR (wang yong)) yang xi test ((kan min) or (chang min)) jeang yean ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang dong) OR (wang yong)) yang xi test ((kan min) or (chang min)) jeang yean ;*.
