Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
vi cua » vai cua
di cua » dai cua, doi cua, de 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 xuc va thanh ((vi cua) OR (di 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 xuc va thanh ((vi cua) OR (di cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((xa hoi) or (mai hoi)). hieu ve cam xuc va thanh ((vi cua) OR (di cua)) triet*.
