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