Perhaps you should try some spelling variations:
gender truong » gender barung, gender typing
truong thanh » luong thanh, truong tran, tran thanh
wang jan » wang ban, wang jun, hwang jane
wang dan » wang ban, wang yidan, wang yang
done sau » done so, done hu, wong sau
done a » done _, zone a, done 5

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

• Performing a fuzzy search may retrieve terms with similar spellings: qian ((wang jan) or (((wang dan) OR (wang yan)))) a gender truong thanh ((done sau) or (done a)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: qian ((wang jan) OR (((wang dan) OR (wang yan)))) a gender truong thanh ((done sau) OR (done a)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian ((wang jan) or (((wang dan) OR (wang yan)))) a gender truong thanh ((done sau) or (done a)) ;".
• Adding a wildcard symbol may retrieve word variants: qian ((wang jan) or (((wang dan) OR (wang yan)))) a gender truong thanh ((done sau) or (done a)) ;*.
