Perhaps you should try some spelling variations:
doanh ban » doanh bat, doanh van, doanh nhan
va doanh » van doanh, vay doanh, va danh
te sach » toc sach
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, me hoi
ve cam » ve cham, ve cac, va cam
cua tu » cua tuc, cua su, cua cu

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) OR (ma hoa)). hieu ve cam duc va doanh ban ((cua te) OR (cua tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((ma hoi) or (ma hoa)). hieu ve cam duc va doanh ban ((cua te) OR (cua tu))~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((ma hoi) or (ma hoa)). hieu ve cam duc va doanh ban ((cua te) OR (cua tu))*.
