using run » during run, using ann, using rs
yang yang » wang yan
kia chang » kia hong, ii chang, jia zhang
dan yang » daun yang, tan yang, adam yang
chang ha » chang mae
using r » using _, using a

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 ((using run) OR (using r)) ((dan yang) or (yang yang)) kia chang ha ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((using run) OR (using r)) ((dan yang) OR (yang yang)) kia chang ha ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((using run) OR (using r)) ((dan yang) or (yang yang)) kia chang ha ;*".
