Perhaps you should try some spelling variations:
seine kunden » seine kinder, neue kunden, die kunden
done using » line using, move using
kunden man » kunden am
done sin » dong sin, done fix
man cong » yan cong, man houng, man can
a seine » la seine, _ seine, 1 seine
a a » a la

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((done sin) OR (done using))) or (done so)) a a seine kunden man cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((done sin) OR (done using))) OR (done so)) a a seine kunden man cong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((done sin) OR (done using))) or (done so)) a a seine kunden man cong shu ;*".
