Perhaps you should try some spelling variations:
costs coping » costs keeping, costs china, costs using
costs timing » costs arising, costs driving, costs missing
hua credit » dual credit, a credit, du credit
ida credit » ida credits, a credit, de credit
yang yang » wang yang, wang yan
yang yala » yang yao, yang all, yang dali

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

• Performing a fuzzy search may retrieve terms with similar spellings: yang yang yala ((hua credit) or (ida credit)) trading ((costs coping) OR (costs timing)) shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang yang yala ((hua credit) OR (ida credit)) trading ((costs coping) OR (costs timing)) shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang yala ((hua credit) or (ida credit)) trading ((costs coping) OR (costs timing)) shu ;*".
