Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
hang moi » hang doi, hang loi, hanh moi
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
dam tuc » dam thuc, dao tuc, nam thuc
tu san » thu san, tu ban, tu can
dam tu » nam tu, cam tu, tam tu
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 ((dam tuc) or (dam tu)) ngan hang moi ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang xa hoi. hieu ve ((dam tuc) OR (dam tu)) ngan hang moi ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang xa hoi. hieu ve ((dam tuc) or (dam tu)) ngan hang moi ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang xa hoi. hieu ve ((dam tuc) or (dam tu)) ngan hang moi ((cua triet) OR (va triet))*.
