Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
nhung cong » dung cong, thong cong, hang cong
doanh cua » doanh luan
tang cua » mang cua, hang cua, tang luan
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cau » toan cau, phan cau, than cap

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)) - hanh ((doanh cua) OR (tang cua)) nhung cong tan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - hanh ((doanh cua) or (tang cua)) nhung cong tan than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - hanh ((doanh cua) or (tang cua)) nhung cong tan than cau*.
