Perhaps you should try some spelling variations:
jeong yeon » jeong hyeok, jeang yean, jeong dahyeon
seung yeon » seung joon, seung won, seung youn
dong myron » dong myeon
yao yang » yang yang
dan yang » daun yang, tan yang, wang yang
yi test » ai test, i test, ii test
test 5 » test _, test 4
5 tin » 5 thin, 5 ein, _ tin

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

• Performing a fuzzy search may retrieve terms with similar spellings: wing ((yao yang) or (dan yang)) yi test 5 tin ((((jeong yeon) OR (seung yeon))) or (dong myron)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((yao yang) OR (dan yang)) yi test 5 tin ((((jeong yeon) OR (seung yeon))) OR (dong myron)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yao yang) or (dan yang)) yi test 5 tin ((((jeong yeon) OR (seung yeon))) or (dong myron)) ;*".
