Perhaps you should try some spelling variations:
su triet » su tien, ve triet
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
cau xuc » cam xuc, cau luc, cau truc
va hanh » van hanh, va thanh, va danh
van anh » van thanh, tuan anh, van minh
su viet » so viet
va cau » van cau, va cac, va dau
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: tu sach ky nang x hoi. lieu va cau xuc ((va hanh) or (van anh)) ki ((su triet) OR (su viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang x hoi. lieu va cau xuc ((va hanh) OR (van anh)) ki ((su triet) OR (su viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang x hoi. lieu va cau xuc ((va hanh) or (van anh)) ki ((su triet) OR (su viet))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang x hoi. lieu va cau xuc ((va hanh) or (van anh)) ki ((su triet) OR (su viet))*.
