Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vi » hanh vi, thanh va, thanh ve
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
mai hoi » mai khoi, dai hoi, lai hoi
ve cam » ve cham, va cam, ve cai
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua

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 sach y nang ((xa hoi) OR (mai hoi)). hieu ((ve cam) OR (ve cac)) xuc va thanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((xa hoi) or (mai hoi)). hieu ((ve cam) OR (ve cac)) xuc va thanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((xa hoi) or (mai hoi)). hieu ((ve cam) OR (ve cac)) xuc va thanh vi cua triet*.
