Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
thien van » thi van
van thanh » ban thanh, van tuan
su triet » su viet, su tien, ve triet
thanh vi » hanh vi, thanh va, thanh ve
nam thuc » nam thuoc, am thuc, nam thu
nang co » nang cao, nang doc, nang noi
nam luc » nang luc, nhan luc, nam duoc
sac ky » cac ky, sai ky
co hoi » co hoc, co loi
te sac » te sach, te cac, te san

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 ky nang co hoi. thien van ((nam luc) or (nam thuc)) van thanh vi ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang co hoi. thien van ((nam luc) OR (nam thuc)) van thanh vi ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang co hoi. thien van ((nam luc) or (nam thuc)) van thanh vi ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang co hoi. thien van ((nam luc) or (nam thuc)) van thanh vi ((cua triet) OR (su triet))*.
