Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
xanh di » vanh dai, xanh tai
danh di » danh du, danh dien, danh gia
cac loc » cac lop, cac toc, cac hoc
hieu ve » hieu va, hieu van
loc va » hoc va, luc va
ve cac » va cac, vien cac
te cac » tu cac, te cao, de cac
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 cac ky nang x hoi. hieu ve cac loc va ((danh di) or (xanh di)) ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky nang x hoi. hieu ve cac loc va ((danh di) OR (xanh di)) ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky nang x hoi. hieu ve cac loc va ((danh di) or (xanh di)) ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: te cac ky nang x hoi. hieu ve cac loc va ((danh di) or (xanh di)) ((cua triet) OR (va triet))*.
