Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
dinh dai » sinh dai, dinh dao, dinh tai
dinh dat » dinh ket, dinh van, dinh lam
van dam » van nam, van dao, van dau
thuc va » thuc vat, thuc dan, thuc day
van am » van nam, van lam, van ai
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: tu cac ky nang x hoi. hieu ((van am) or (van dam)) thuc va ((dinh dai) OR (dinh dat)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang x hoi. hieu ((van am) OR (van dam)) thuc va ((dinh dai) OR (dinh dat)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang x hoi. hieu ((van am) or (van dam)) thuc va ((dinh dai) OR (dinh dat)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang x hoi. hieu ((van am) or (van dam)) thuc va ((dinh dai) OR (dinh dat)) cua triet*.
