Perhaps you should try some spelling variations:
nhung chong » nhung cong, nhung phong, nhung phuong
theo chieu » theo tieu, ho chieu, theo chu
canh doanh » hanh doanh, chinh doanh, doanh doanh
phung cong » nhung cong, phong cong, dung cong
hoc thieu » toc thieu, hoc hien
doanh ban » doanh bat, doanh van, doanh nhan
manh van » anh van, menh van, canh van

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: ((theo chieu) OR (hoc thieu)) xanh - canh doanh ban ((phung cong) OR (nhung chong)) manh van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (hoc thieu)) xanh - canh doanh ban ((phung cong) OR (nhung chong)) manh van ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (hoc thieu)) xanh - canh doanh ban ((phung cong) OR (nhung chong)) manh van ban*.
