Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
lam thuc » lam thuoc, am thuc, nam thuc
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va danh » va dan, va hanh, dia danh
va dinh » van dinh, va kinh, va tinh
te sac » te sach, te san
te cac » tu cac, ve cac, te cao
va lam » van lam, va lap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((te sac) or (te cac)) ky nang xa hoi. hieu va lam thuc ((va danh) OR (va dinh)) dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te cac)) ky nang xa hoi. hieu va lam thuc ((va danh) OR (va dinh)) dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te cac)) ky nang xa hoi. hieu va lam thuc ((va danh) OR (va dinh)) dai cua triet".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (te cac)) ky nang xa hoi. hieu va lam thuc ((va danh) OR (va dinh)) dai cua triet*.
