Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
thanh doi » thanh loi, thanh moi, thanh do
va triet » va thiet, va trien, ve triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
tuc gia » tac gia, toc gia, luc gia
duc gia » quoc gia
te san » te ban, ke san, tu san
san ky » sang ky, van ky, dan ky
ve cam » ve cham, ve cac, 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 san ky nang xa hoi. hieu ve cam ((tuc gia) or (duc gia)) thanh doi ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky nang xa hoi. hieu ve cam ((tuc gia) OR (duc gia)) thanh doi ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky nang xa hoi. hieu ve cam ((tuc gia) or (duc gia)) thanh doi ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: te san ky nang xa hoi. hieu ve cam ((tuc gia) or (duc gia)) thanh doi ((cua triet) OR (va triet))*.
