Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
nang ma » tang ma, sang ma, nang cao
hieu va » lieu va, hieu qua
cao xuc » cam xuc, cao duc, cao suc
xa hanh » xa thanh, xa khanh, va hanh
vai cua » hai cua, lai cua, bai cua
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa
va cao » va cac, va co, va dao
xuc xa » tuc xa, buc xa
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: tu sach y nang ma hoi. hieu va cao xuc xa hanh ((vi cua) OR (((vai cua) OR (dai cua)))) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang ma hoi. hieu va cao xuc xa hanh ((vi cua) or (((vai cua) OR (dai cua)))) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ma hoi. hieu va cao xuc xa hanh ((vi cua) or (((vai cua) OR (dai cua)))) tre*.
