Perhaps you should try some spelling variations:
hanh doanh » hang doanh, chinh doanh, doanh doanh
chieu xanh » chieu sach, chieu sang, chieu tinh
doanh luan » doanh nhan
nhung cong » dung cong, thong cong, nhung don
hieu xanh » hieu manh, hieu nganh, dieu hanh
hang cong » dang cong, hang nong, bang cong
dan chon » dan chan, dan cho, dinh chon
chon tu » con tu, cho tu, choi 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: doc ((hieu xanh) OR (chieu xanh)) - hanh doanh luan ((nhung cong) OR (hang cong)) dan chon tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) or (chieu xanh)) - hanh doanh luan ((nhung cong) OR (hang cong)) dan chon tu~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu xanh) or (chieu xanh)) - hanh doanh luan ((nhung cong) OR (hang cong)) dan chon tu*.
