Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, ho chieu, mot chieu
tranh cua » doanh cua, manh cua
dang cong » dung cong
doi chi » doi khi
van tai » von tai, van tuan
tai cau » tai cac, tai cao

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) OR (doi chi)) xanh - hanh tranh cua ((nhung cong) OR (dang cong)) van tai cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doi chi)) xanh - hanh tranh cua ((nhung cong) or (dang cong)) van tai cau~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (doi chi)) xanh - hanh tranh cua ((nhung cong) or (dang cong)) van tai cau*.
