chang hay » change has, chang hee, chang ly
chang mae » changes made
yang jin » yang jie, yang jun, ying jin
4 wang » _ wang, x wang, l wang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yang yang) or (dong yang)) 4 wang yang jin ((((chang hay) OR (chang ha))) or (chang mae)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang yang) OR (dong yang)) 4 wang yang jin ((((chang hay) OR (chang ha))) OR (chang mae)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang yang) or (dong yang)) 4 wang yang jin ((((chang hay) OR (chang ha))) or (chang mae)) ;*".
