Perhaps you should try some spelling variations:
vay doanh » van doanh, ly doanh, voi doanh
thu hang » thi hang, thuc hanh, thu huong
va doanh » van doanh, va danh, hoa doanh
tu sach » thu sach, su sach, te sach
van cua » vang cua, ban cua, dan cua
lam xuc » cam xuc, lam duoc
va lam » van lam, va lap
cua te » cua tu

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 ((thu hang) OR (thu ban)) xa hoi. lieu va lam xuc ((va doanh) OR (vay doanh)) van cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((thu hang) or (thu ban)) xa hoi. lieu va lam xuc ((va doanh) OR (vay doanh)) van cua te~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((thu hang) or (thu ban)) xa hoi. lieu va lam xuc ((va doanh) OR (vay doanh)) van cua te*.
