Perhaps you should try some spelling variations:
te sach » toc sach
sach ky » sac ky, sach y, sach ty
cua tre » cua te, cua triet, dua tren
hanh ve » hanh vi, hanh va, hanh kem
dua ban » dia ban, cua ban, qua ban
cuu tre » cau tren, cau treo
cuc ban » cua ban, cac ban, cuu ban
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
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 ky nang x hoi. hieu ve cam ((cuc ban) or (dua ban)) hanh ve ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang x hoi. hieu ve cam ((cuc ban) OR (dua ban)) hanh ve ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang x hoi. hieu ve cam ((cuc ban) or (dua ban)) hanh ve ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang x hoi. hieu ve cam ((cuc ban) or (dua ban)) hanh ve ((cua tre) OR (cuu tre))*.
