Perhaps you should try some spelling variations:
debt during » debate during, debt turning, neet during
crises how » crisis how
fan yang » dan yang, tan yang, wang yang
fan ying » fan xing, tan ying, jin ying
ran ying » tan ying, jin ying, gao 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 (((fan ying) OR (ran ying)))) jie debt during crises how race ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai ((fan yang) or (((fan ying) OR (ran ying)))) jie debt during crises how race ;~".
• Adding a wildcard symbol may retrieve word variants: wai ((fan yang) or (((fan ying) OR (ran ying)))) jie debt during crises how race ;*.
