Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trinh » canh tranh, hanh chinh
chau tinh » cuu tinh, ha tinh, cua tinh
dung cong » dung trong
cong tac » cong ty
tac tran » tan tran, tac trai, tac tren
tran cau » tran chau, toan cau, ran cau
va dung » van dung, va duong, vat dung

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: doi ((chieu xanh) OR (chau tinh)) - ((thanh cong) OR (hanh trinh)) va dung cong tac tran cau~.
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chau tinh)) - ((thanh cong) or (hanh trinh)) va dung cong tac tran cau*.
