Perhaps you should try some spelling variations:
thieu nien » thien nhien
nien cac » vien cac, dien cac, bien cac
van dung » van dong, xay dung, tin dung
su triet » su viet, su tien, ve triet
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
cac xuc » cam xuc, cac nuoc, chat xuc
va dung » va duong, vat dung, va ung
y nang » ky nang, ly nang, v nang

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 y nang xa hoi. thieu nien cac xuc ((va dung) OR (van dung)) tai ((su triet) or (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. thieu nien cac xuc ((va dung) OR (van dung)) tai ((su triet) OR (va thiet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. thieu nien cac xuc ((va dung) OR (van dung)) tai ((su triet) or (va thiet))".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. thieu nien cac xuc ((va dung) OR (van dung)) tai ((su triet) or (va thiet))*.
