Perhaps you should try some spelling variations:

thieu bien » tieu bieu, hien bien, hieu hien
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, va danh
nang xa » nang x, lang xa, nang ma
te sach » toc sach
xuc va » duc va, tuc va, luc va
vai va » mai va, dai va, lai va
hai va » hai van, thai va, hoi va

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 bien) OR (thieu nien)) cam xuc va hanh ((vai va) or (hai va)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. ((thieu bien) OR (thieu nien)) cam xuc va hanh ((vai va) OR (hai va)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. ((thieu bien) OR (thieu nien)) cam xuc va hanh ((vai va) or (hai va)) triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. ((thieu bien) OR (thieu nien)) cam xuc va hanh ((vai va) or (hai va)) triet*.
