3 changes » 2 changes, 3 change, 4 changes
daud yang » daun yang, daud wan, du yang
yan juan » san juan, yan guan, yan yuan
wan yan » wang yan, nan yan, wai yan
yi yang » yin yang, yu yang, ying yang
yi gang » ii gang, i gang, li gang
juan m » juan j, juan a, juan c

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 juan m daud yang ((((yi yang) OR (yi gang))) or (3 changes)) (hai or hadi) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan juan m daud yang ((((yi yang) OR (yi gang))) OR (3 changes)) (hai OR hadi) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan juan m daud yang ((((yi yang) OR (yi gang))) or (3 changes)) (hai or hadi) ;*".
