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

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 ((((yang ai) OR (yang li))) or (yang xi)) ((test kaw) or (test a)) kin keong yeon ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ying ((((yang ai) OR (yang li))) OR (yang xi)) ((test kaw) OR (test a)) kin keong yeon ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying ((((yang ai) OR (yang li))) or (yang xi)) ((test kaw) or (test a)) kin keong yeon ;*".
