Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chiet tach » chieu sach
nhung cong » dung cong, thong cong, hang cong
hanh hang » thanh hang, hang hang, hanh han
cua nhung » va nhung
hang cua » mang cua, hang ca, huong cua
cong tan » cong tac, cong san, cong thanh
quan tap » quan tai, quan lap, quan tay
quan tam » quan tai, quan am, quan nam

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 ((chieu xanh) OR (chiet tach)) - hanh hang cua nhung cong tan ((quan tap) OR (quan tam))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chiet tach)) - hanh hang cua nhung cong tan ((quan tap) OR (quan tam))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chiet tach)) - hanh hang cua nhung cong tan ((quan tap) OR (quan tam))*.
