Perhaps you should try some spelling variations:
thieu nien » thien nhien
cua triet » cua viet, su triet, va triet
nien cac » vien cac, dien cac, bien cac
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa

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

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