Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
va thanh » gia thanh, va tinh, le thanh
cua viet » hoa viet, cua vat, cua dieu
sach ky » sac ky, sach y, sach ty
te sach » toc sach
cac xuc » cam xuc, cac nuoc, chat xuc
van cac » van hac, van cau, van bac
thi van » thi lan, thi hanh, thi nang
nang xa » nang x, lang xa, nang ma
ca viet » va viet, co viet, hoa viet

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. thi van cac xuc ((va thanh) or (ban thanh)) lap ((cua viet) OR (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. thi van cac xuc ((va thanh) OR (ban thanh)) lap ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. thi van cac xuc ((va thanh) or (ban thanh)) lap ((cua viet) OR (ca viet))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. thi van cac xuc ((va thanh) or (ban thanh)) lap ((cua viet) OR (ca viet))*.
