Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung won
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
yang ai » yang di, yang xi, yang yi
ai test » api test, i test, ii test
kaw min » kyaw min, law main
kan min » han min, kian ming, kyaw min

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 ai test ((kaw min) OR (kan min)) seung yeon ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong yang ai test ((kaw min) or (kan min)) seung yeon ;*.
