Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thien van » thi van
thanh vi » hanh vi, thanh va, thanh ve
luoc van » luoc can, luoc va, luot van
nang co » nang cao, nang doc, nang noi
te cach » ve cach, te sach, tu cach
luc van » luu van, duc van, luc va
co hoi » co hoc, co loi
vi cua » vai cua, di cua
te cac » tu cac, ve cac, te cao

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 cac) OR (te cach)) ky nang co hoi. thien van nam ((luc van) OR (luoc van)) thanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) or (te cach)) ky nang co hoi. thien van nam ((luc van) OR (luoc van)) thanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((te cac) or (te cach)) ky nang co hoi. thien van nam ((luc van) OR (luoc van)) thanh vi cua triet*.
