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, wang yang
tan yang » dan yang, tan ying, tao yang
tan yong » tan hong, tan kong, tan ying

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