Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
hanh tang » hanh trang, anh tang, hanh tung
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cau » toan cao, toan ban, toan tap

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