Perhaps you should try some spelling variations:
keong yeon » jeong yeon, seung yeon
wang ying » wang yong, wang jing, wang ning
wang yang » wang yan, wang liang, wang yanling
kin keong » king kong, min jeong
yang jui » yang judy, yang di, yang yi
test kaw » test kit, test awt, test ke
yang xi » yang di, yang yi
test a » test _, test 4, test 5

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 yang)) ((yang xi) OR (yang jui)) ((test kaw) OR (test a)) kin keong yeon ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ying) OR (wang yang)) ((yang xi) or (yang jui)) ((test kaw) or (test a)) kin keong yeon ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ying) OR (wang yang)) ((yang xi) or (yang jui)) ((test kaw) or (test a)) kin keong yeon ;*.
