Perhaps you should try some spelling variations:
dong thanh » truong thanh
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu han, chu van
tang cua » mang cua, hang cua, tang luan
cong dan » cong san, cong tan, huong dan
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: theo ((chu xanh) OR (chu manh)) - hanh tang cua nhung ((cong dan) OR (dong thanh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chu manh)) - hanh tang cua nhung ((cong dan) or (dong thanh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chu manh)) - hanh tang cua nhung ((cong dan) or (dong thanh)) toan cau*.
