Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
thanh tran » thanh trang, thanh toan, thanh tra
hanh tang » hanh trang, anh tang, hanh mang
nong cong » cong cong, tong cong, dong cong
nang cong » nang song, dang cong, bang cong
tang cua » mang cua, hang cua, tang luan
tran cau » tran chau, toan cau, ran cau

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 (chieu sach)) - hanh tang cua ((nong cong) OR (nang cong)) thanh tran cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sach)) - hanh tang cua ((nong cong) OR (nang cong)) thanh tran cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sach)) - hanh tang cua ((nong cong) OR (nang cong)) thanh tran cau*.
