Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thien van » thi van
thanh va » thanh van, thanh ha, thanh ve
nam thuc » nam thuoc, am thuc, nam thu
nam duc » nam duoc, pham duc, nam buoc
nang co » nang cao, nang doc, nang noi
hanh va » hang va, hanh vi
sac ky » cac ky, sai ky
co loi » co hoi
te sac » te sach, te cac, te san

You may be able to get more results by adjusting your search query.

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