Perhaps you should try some spelling variations:
yong yang » dong yang, ying yang, kyoung yang
yang yang » wang yang, wang yan
gong meng » gong gang
gong min » song min, song ming, gong si
jong min » song min, song ming, cog min
long du » long d, long do, long run
li li » li lin, li l, li lu

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yong yang) OR (yang yang)) li li ((((gong min) or (gong meng))) or (jong min)) long du ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong yang) OR (yang yang)) li li ((((gong min) OR (gong meng))) OR (jong min)) long du ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) OR (yang yang)) li li ((((gong min) or (gong meng))) or (jong min)) long du ;*".
