Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung won
wang ying » wang yang, wang yong, wang ning
wang jing » wang ning, wang liang, wang yang
jui test » ai test, api test, ii test
kan min » kian ming, kyaw min, tang min
han min » han men, chan ming, chang min
i test » ai test, i testi, ii test

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 ying) OR (wang jing)) chang ((jui test) OR (i test)) ((kan min) OR (han min)) seung yeon ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ying) OR (wang jing)) chang ((jui test) or (i test)) ((kan min) or (han min)) seung yeon ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ying) OR (wang jing)) chang ((jui test) or (i test)) ((kan min) or (han min)) seung yeon ;*.
