Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, canh tranh, hanh trinh
hanh mang » nhanh mang, nhanh lang, thanh hang
cong cong » cong dong, trong cong, dung cong
chu manh » ho manh, chu han, chu van
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh 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: theo ((chieu xanh) OR (chu manh)) - ((hanh trang) OR (hanh mang)) cua cong cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chu manh)) - ((hanh trang) or (hanh mang)) cua cong cong dan toan cau*.
