Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh mang » nhanh mang, hanh trang, nhanh lang
dung cong » dung trong
chu xanh » chu manh, chua xang, chuc danh
mang qua » mang cua, mang vua, nang quan
qua dung » quang dung, su dung, qua song
cong san » cong tac
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac

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 ((chu xanh) OR (chieu xanh)) - hanh mang qua dung cong san ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chieu xanh)) - hanh mang qua dung cong san ((than cau) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chieu xanh)) - hanh mang qua dung cong san ((than cau) OR (than cap))*.
