changes were » changes we, changes west, changes due
song ming » song bing, song min, gong min
were bin » wer bin, where big, wei bin
bin yang » yin yang, bin zhang, ying yang
yang kim » yong kim, kang kim, hyung kim
jong min » gong min, song min, jeong mi
cog min » gong min, song min
wang » wing, wan

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

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or lang) your changes were bin yang kim ((((jong min) OR (song ming))) or (cog min)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) your changes were bin yang kim ((((jong min) OR (song ming))) OR (cog min)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) your changes were bin yang kim ((((jong min) OR (song ming))) or (cog min)) ;*".
