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
yi test » ai test, i test, ein test
ii test » ai test, i test, api test
kaw min » kyaw min, kan min, law main
han men » can men, han en, han 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 ((yi test) OR (ii test)) ((kaw min) OR (han men)) seung yeon ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong yang ((yi test) or (ii test)) ((kaw min) or (han men)) seung yeon ;*.
