dong hua » tong hui, dong hoi, dong xu
ren weng » den weg
weng qin » wang qin, wen ein, weng yi
long sau » wong sau, long span, long way
haul » hall, paul, hail

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang fan) or (wang yang)) ((dong hua) or (wang hua)) ren weng qin ((long sau) OR (long haul)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang fan) OR (wang yang)) ((dong hua) OR (wang hua)) ren weng qin ((long sau) OR (long haul)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang fan) or (wang yang)) ((dong hua) or (wang hua)) ren weng qin ((long sau) OR (long haul)) ;*".
