Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung youn
seung won » seung joon, seung youn, myung won
yan yang » yang yang, yao yang, dan yang
kyaw min » kan min
xi test » ai test, i test, ein test
ii test » ai test, i test, api test
wang » wing, wan, lang

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