wang ying » wang yang, wang yong, wang jing
yang li » yang lin, yang di, yang xi
yang yi » yang di, yang xi, yang jui
a main » 1 main, 2 main
a min » a mini, a mine, a mind

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