Perhaps you should try some spelling variations:
thieu bien » thieu nien, tieu bieu, hien bien
su triet » su tien, ve triet
bien cac » vien cac, dien cac, bien ca
te sach » toc sach
va danh » va dinh, va dan, dia danh
va hanh » van hanh, va thanh, ban hanh
sach ty » sach y, sach tu, sach thu
cac xuc » cam xuc, cac nuoc, chat xuc
ty nang » ky nang, ty xang, ty hang
su viet » so viet
x hoi » xa hoi, o hoi, x ho

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 ty nang x hoi. thieu bien cac xuc ((va hanh) or (va danh)) va ((su triet) OR (su viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang x hoi. thieu bien cac xuc ((va hanh) OR (va danh)) va ((su triet) OR (su viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang x hoi. thieu bien cac xuc ((va hanh) or (va danh)) va ((su triet) OR (su viet))*".
