Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung won, seung youn
seung joon » kyung joon, seung won, seung youn
wang wang » wang liang, wang yan, wang yong
wang yang » wang yan, wang liang, wang yanling
test kaw » test a, test kit, test awt
ii test » ai test, i test, api test
kaw mun » kyaw min
yan ii » yan zi

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 wang) OR (wang yang)) yan ii test kaw mun ((seung joon) OR (seung yeon)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang yang)) yan ii test kaw mun ((seung joon) OR (seung yeon)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang yang)) yan ii test kaw mun ((seung joon) OR (seung yeon)) ;*.
