Perhaps you should try some spelling variations:
leong yeon » jeong yeon, seung yeon
wang yong » wang hyoung, wang yan, wang shiyong
wang yang » wang yan, wang liang, wang yanling
mun leong » min jeong
api test » i test, ii test
ai test » i test, ii test, ein test
kaw mun » kyaw min

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yong) OR (wang yang)) yang ((api test) or (ai test)) kaw mun leong yeon ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yong) OR (wang yang)) yang ((api test) OR (ai test)) kaw mun leong yeon ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) OR (wang yang)) yang ((api test) or (ai test)) kaw mun leong yeon ;*".
