Perhaps you should try some spelling variations:
jeong shu » jeong su, cong shu
song min » song ming, gong min, song shin
song jin » shang jin, song shin, song bing
jong min » gong min, song ming, cog min
yang dr » yang di, yang du
yang d » yang di, yang du, yang _
wang » wing, wan, lang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((yang dr) OR (yang d)) e ((((song min) OR (song jin))) OR (jong min)) jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yang dr) OR (yang d)) e ((((song min) or (song jin))) or (jong min)) jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((yang dr) OR (yang d)) e ((((song min) or (song jin))) or (jong min)) jeong shu ;*.
