Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
ban thanh » ban hanh, ban hang
thanh tai » thanh hai, thanh toan, doanh tai
cham cuc » pham cuc, pham chuc, kham cuoc
cham cuu » cap cuu, chat cua
cua tre » cua te, cuu tre, dua tren
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky nang xa hoi. hieu ve ((cham cuc) OR (cham cuu)) ban thanh tai ((cua triet) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang xa hoi. hieu ve ((cham cuc) OR (cham cuu)) ban thanh tai ((cua triet) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang xa hoi. hieu ve ((cham cuc) OR (cham cuu)) ban thanh tai ((cua triet) or (cua tre))*".
