Perhaps you should try some spelling variations:
chon chien » chong thien, cuoc chien, can chien
chien xanh » chieu xanh, chien tranh, hien hanh
hanh dong » anh dong, ha dong
anh cong » hanh cong, anh dong, thanh cong
cong tac » cong ty
tac toan » tap toan, tam toan, hach 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: chon chien xanh - ((anh cong) OR (hanh dong)) ((cua nhung) OR (va nhung)) cong tac toan cau~.
• Adding a wildcard symbol may retrieve word variants: chon chien xanh - ((anh cong) or (hanh dong)) ((cua nhung) or (va nhung)) cong tac toan cau*.
