Perhaps you should try some spelling variations:
doanh mang » doanh sang, doanh quang, doanh ban
ve doanh » va doanh, de doanh, te doanh
mang cua » manh cua, dung cua, ban cua
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
hieu ve » hieu van
y nang » ky nang, ly nang, v nang
cuu ve » cuu va
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: su sach y nang xa hoi. ((hieu va) OR (hieu ve)) cap cuu ve doanh mang cua te~.
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. ((hieu va) or (hieu ve)) cap cuu ve doanh mang cua te*.
