Perhaps you should try some spelling variations:
doanh ban » doanh bat, doanh van, doanh nhan
nang xa » nang x, lang xa, nang ma
van cac » van hac, van bac, dan cac
van cau » van dau, van hau, van chat
ban cua » ban quan
toc va » hoc va, tuc va, loc va
toc ta » toc tay, toc thai
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 cac ky nang xa hoi. hieu ((van cac) OR (van cau)) ((toc va) OR (toc ta)) doanh ban cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang xa hoi. hieu ((van cac) or (van cau)) ((toc va) OR (toc ta)) doanh ban cua te~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang xa hoi. hieu ((van cac) or (van cau)) ((toc va) OR (toc ta)) doanh ban cua te*.
