Perhaps you should try some spelling variations:
jeang yean » jeong yeon
chan ming » kian ming, chan eng, chan fong
wang yong » wang yang, wang hyoung, wang yan
yong yan » yang yang, dong yang, ying yang
xi test » ai test, ii test, ein test
han min » han men, kan min, chang min
i test » ai test, i testi, ii test

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 yong yan ((xi test) OR (i test)) ((new spain) OR (((han min) OR (chan ming)))) jeang yean ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yan ((xi test) or (i test)) ((new spain) or (((han min) OR (chan ming)))) jeang yean ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yan ((xi test) or (i test)) ((new spain) or (((han min) OR (chan ming)))) jeang yean ;*.
