Perhaps you should try some spelling variations:
jeang yean » jeong yeon
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
law main » law pain, law making, new main
di test » ai test, ii test, disk test
kan min » han min, kian ming, kyaw 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 yang ((di test) OR (i test)) ((kan min) OR (law main)) jeang yean ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yang ((di test) OR (i test)) ((kan min) or (law main)) jeang yean ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yang ((di test) OR (i test)) ((kan min) or (law main)) jeang yean ;*.
