Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung won
wang ying » wang yang, wang yong, wang liang
wang ning » wang liang, wang yang, wang yong
wang jing » wang liang, wang yang, wang yong
min seung » min jeong
test kaw » test a, test kit, test awt
yang yi » yang di, yang xi, yang jui
test 4 » test _

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang ying) OR (wang ning))) or (wang jing)) yang yi ((test kaw) or (test 4)) min seung yeon ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang ying) OR (wang ning))) OR (wang jing)) yang yi ((test kaw) OR (test 4)) min seung yeon ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang ying) OR (wang ning))) or (wang jing)) yang yi ((test kaw) or (test 4)) min seung yeon ;*".
