Perhaps you should try some spelling variations:
pay breaking » past breaking, path breaking, map breaking
yang yang » wang yang, wang yan
qian dan » qian yan, liang dan, qian wang
yang can » yang fan, yang dean, yang jin
bad bank » bad banks, land bank, bond bank
bid bond » bid bonds, old bond
swap » swaps

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: qian dan ((yang can) OR (yang yang)) pay breaking ((bad bank) OR (bid bond)) swap ;~.
• Adding a wildcard symbol may retrieve word variants: qian dan ((yang can) or (yang yang)) pay breaking ((bad bank) or (bid bond)) swap ;*.
