Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh hung » thanh huong, thanh tung, thanh trung
doi chieu » doc hieu, doi chi, ho chieu
hanh dung » thanh dung, anh dung, hanh dong
cua tong » cua cong, cua dong, cua nong
cong tyg » cong tang, cong tac, cong tan
than cau » toan cau, phan cau, than cap

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 tinh - ((hanh dung) OR (thanh hung)) cua tong ((cong ty) OR (cong tyg)) than cau~.
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - ((hanh dung) or (thanh hung)) cua tong ((cong ty) or (cong tyg)) than cau*.
