Perhaps you should try some spelling variations:
debat during » debate during, debt during, exit during
crises how » crisis how
jie debat » le debat
how space » how race
fan yang » dan yang, fan ying, tan yang
ran ying » fan ying, jin ying, gao ying
tan ying » fan ying, tan yang, tan yong

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