cua nhung » va nhung
chu xanh » chu manh, chieu xanh, chuc danh
tang cua » mang cua, hang cua, tang luan

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: cua ((chu xanh) OR (chua xang)) - hanh tang cua nhung ((cong san) OR (cong tac)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cua ((chu xanh) OR (chua xang)) - hanh tang cua nhung ((cong san) or (cong tac)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: cua ((chu xanh) OR (chua xang)) - hanh tang cua nhung ((cong san) or (cong tac)) toan cau*.
