long grain » long chain, long green, long trail
yang muxi » yang xi, yang hui, yang mu
chang mae » chang ha, changes made
long tail » long haul
wang yao » wang yan, yang yao, gang yao
yang jui » yang judy, yang di, yang xi

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

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