Perhaps you should try some spelling variations:
te sach » toc sach
nang ma » tang ma, sang ma, nang cao
lai cua » hai cua, lai chau, thai cua
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
luc va » duc va, tuc va, loc va
xuc va » duc va, tuc va, xac va
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa

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 ma hoi. hieu ve chat ((xuc va) OR (luc va)) hanh ((lai cua) OR (dai cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. hieu ve chat ((xuc va) or (luc va)) hanh ((lai cua) OR (dai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. hieu ve chat ((xuc va) or (luc va)) hanh ((lai cua) OR (dai cua)) te*.
