Perhaps you should try some spelling variations:
equal credit » dual credit, equity credit, rural credit
costs along » costs among, costs longer
hua credit » dual credit, a credit, du credit
wang yang » wang yan, wang liang, wang yanling
along shu » along nhue, cong shu, along who
yang yi » yang di, yang xi, yang jui

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yi ((hua credit) OR (equal credit)) trading costs along shu ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang yi ((hua credit) or (equal credit)) trading costs along shu ;*.
