Perhaps you should try some spelling variations:
debt during » debate during, debt turning, neet during
crises how » crisis how
fan yang » tan yang, wang yang, yang yang
dan yang » daun yang, tan yang, wang yang
fan ying » fan xing, ran ying, tan ying
jie debt » aid debt, due debt
how race » how space

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: wai ((((fan yang) OR (dan yang))) OR (fan ying)) jie debt during crises how race ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai ((((fan yang) OR (dan yang))) or (fan ying)) jie debt during crises how race ;~".
• Adding a wildcard symbol may retrieve word variants: wai ((((fan yang) OR (dan yang))) or (fan ying)) jie debt during crises how race ;*.
