Perhaps you should try some spelling variations:
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
vai cua » dai cua, hai cua, lai cua
sach 2 » sach y
2 nang » v nang
ve cam » ve cham, ve cac, va cam
xuc va » tuc va, luc va, xac va
vi 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 2 nang xa hoi. hieu ve cam ((xuc va) OR (duc va)) hanh ((vi cua) OR (vai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach 2 nang xa hoi. hieu ve cam ((xuc va) or (duc va)) hanh ((vi cua) OR (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: te sach 2 nang xa hoi. hieu ve cam ((xuc va) or (duc va)) hanh ((vi cua) OR (vai cua)) tre*.
