Perhaps you should try some spelling variations:
seung youn » seung joon, seung won, seung yeon
wang liang » wang yang
jeong yeon » jeong hyeok, jeang yean, seung yeon
wang yong » wang yang, wang hyoung, wang yan
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 liang) OR (wang yong)) yan ii test kaw mun ((seung youn) OR (jeong yeon)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yong)) yan ii test kaw mun ((seung youn) or (jeong yeon)) ;*.
