Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
ban danh » ban doanh, ban hanh, ban dan
va triet » va thiet, va trien, ve triet

lam xuc » cam xuc, lam duoc
van lam » van nam
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang xa hoi. hieu van lam xuc ban danh vi ((((cua triet) OR (va triet))) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. hieu van lam xuc ban danh vi ((((cua triet) OR (va triet))) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang xa hoi. hieu van lam xuc ban danh vi ((((cua triet) OR (va triet))) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang xa hoi. hieu van lam xuc ban danh vi ((((cua triet) OR (va triet))) or (cua te))*.
