Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
khong cong » thong cong, khong cang, chong cong
cong thanh » dong thanh, cong trinh, cong tan
thanh toan » thanh hoa, thanh san, tinh toan
hang hai » hoang hai, hang tai, thanh hai
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu xanh) OR (chieu sach)) - hanh ((hang hai) or (hang va)) khong cong thanh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - hanh ((hang hai) OR (hang va)) khong cong thanh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - hanh ((hang hai) or (hang va)) khong cong thanh toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - hanh ((hang hai) or (hang va)) khong cong thanh toan cau*.
