Perhaps you should try some spelling variations:
sudan debt » sudan der, sudan west
amin hong » min hong, among hong, asia hong
tin hong » tan hong, kia hong, thi hong
yang xi » yang yi, yang jui
yang ka » yang fan, yang yao
3 sudan » _ sudan, im sudan, _ sudano
debt a » debt _
ag 3 » a 3, ai 3, ad 3

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang xi) or (yang ka))) or (yang di))ag 3 sudan debt a ((amin hong) OR (tin hong)) guan ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang xi) OR (yang ka))) OR (yang di))ag 3 sudan debt a ((amin hong) OR (tin hong)) guan ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang xi) or (yang ka))) or (yang di))ag 3 sudan debt a ((amin hong) OR (tin hong)) guan ;*".
