Perhaps you should try some spelling variations:
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
va danh » va hanh, dia danh, va thanh
va dinh » van dinh, va kinh, va tinh
va dan » ca dan, va dao, va dau
cuc te » cua te, cuc thue, cuc tieu
va am » va lam, va cam

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. lieu va am thuc ((((va danh) OR (va dinh))) or (va dan)) tai cuc te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. lieu va am thuc ((((va danh) OR (va dinh))) OR (va dan)) tai cuc te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. lieu va am thuc ((((va danh) OR (va dinh))) or (va dan)) tai cuc te".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. lieu va am thuc ((((va danh) OR (va dinh))) or (va dan)) tai cuc te*.
