Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
hieu van » hieu va, thien van, lieu va
van hanh » van thanh, ban hanh, van anh
va hanh » va thanh, va danh, ban hanh
cau xuc » cam xuc, cau luc, cau truc
sach ky » sac ky, sach ty, sach kem
lang xa » lang ha, dang xay, lang van
van cau » van dau, van hau, van chat
ki su » ky su

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