dong sink » dong sin, dong bin
dong ping » dong sin, dong bin, dong jung
jeong ghi » hong ghi, jeong mi
dong nan » dong yang, dong sin, dong bin
hua gene » human gene, a gene, hua ren
han min » kan min, chan ming, chang min
han men » can men, han en, can mena

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong nan) or (((dong sink) or (dong ping)))) ya hua gene ((han min) OR (han men)) jeong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (((dong sink) OR (dong ping)))) ya hua gene ((han min) OR (han men)) jeong ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (((dong sink) or (dong ping)))) ya hua gene ((han min) OR (han men)) jeong ghi ;".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (((dong sink) or (dong ping)))) ya hua gene ((han min) OR (han men)) jeong ghi ;*.
