Perhaps you should try some spelling variations:
song bing » song ming, song byung, dong bin
jeong shu » jeong su, cong shu
gong min » jong min, song min, gong meng
wan yan » wang yan, nan yan, wang yang
wai yan » wang yan, wei yang
yang yi » yang di, yang xi, yang jui
yang i » yang di, yang xi, yang li

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wan yan) OR (wai yan)) ((yang i) or (yang yi)) l ((gong min) or (song bing)) jeong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (wai yan)) ((yang i) OR (yang yi)) l ((gong min) OR (song bing)) jeong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) OR (wai yan)) ((yang i) or (yang yi)) l ((gong min) or (song bing)) jeong shu ;*".
