huang yang » huang ying, huang chang, wang yang
debt turns » debt burdens, debt turning
turns back » runs back, turns bad, turning back
bone sar » borne sar, kong sar
i debt » ii debt, 3 debt, 4 debt
bone a » zone a, bone _, done a

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 ((huang yang) OR (huang cheng)) i debt turns back ((bone sar) OR (bone a)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((huang yang) or (huang cheng)) i debt turns back ((bone sar) OR (bone a)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((huang yang) or (huang cheng)) i debt turns back ((bone sar) OR (bone a)) ;*.
