Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
doanh luan » doanh nhan
nhung cong » thong cong, hang cong, nhung don
anh doanh » hanh doanh, anh danh, doanh doanh
dung cong » dung trong
tuan cau » toan cau, quan cau, tuan 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: ho ((chieu xanh) OR (chieu sang)) - anh doanh luan ((nhung cong) OR (dung cong)) anh tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - anh doanh luan ((nhung cong) or (dung cong)) anh tuan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - anh doanh luan ((nhung cong) or (dung cong)) anh tuan cau*.
