Perhaps you should try some spelling variations:
vay doanh » van doanh, ly doanh, voi doanh
doanh dan » doanh ban, doanh van, doanh dao
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang ma » tang ma, sang ma, nang cao
van cac » van cau, van bac, dan cac
van hac » van hoc, van ha, van hai
tuc vay » tuc va, tu vay, tuc xay
dan cua » dan ca, ban cua, dai cua
cua tre » cua te, cuu tre, cua triet
ma hoi » mai hoi, xa hoi, ma hoa

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ma hoi. thien ((van cac) OR (van hac)) tuc vay doanh dan cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ma hoi. thien ((van cac) OR (van hac)) tuc vay doanh dan cua tre*.
