Perhaps you should try some spelling variations:
su triet » su viet, su tien
van hanh » van thanh, ban hanh, van anh
hieu van » hieu va, thien van, lieu va
ve triet » va trien
tu sach » thu sach, su sach, te sach
cau xuc » cam xuc, cau luc, cau truc
van cau » van dau, van hau, van chat
lang xa » lang ha, dang xay, lang van
va hanh » va thanh, va danh, ban hanh
y lang » o lang, _ lang, tay lang

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