Perhaps you should try some spelling variations:
vinh cuu » dinh cuu, sinh cua, dinh cu
te sach » toc sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
hieu va » lieu va, hieu qua
va tham » van tham, va cham, va thanh
xuc va » tuc va, luc va, xac va
vi cuu » vi luu

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 ty xang xa hoi. hieu va tham ((xuc va) OR (duc va)) thanh ((vi cuu) OR (vinh cuu)) thuc~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang xa hoi. hieu va tham ((xuc va) or (duc va)) thanh ((vi cuu) OR (vinh cuu)) thuc~".
• Adding a wildcard symbol may retrieve word variants: te sach ty xang xa hoi. hieu va tham ((xuc va) or (duc va)) thanh ((vi cuu) OR (vinh cuu)) thuc*.
