Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh trang » thanh trung, canh tranh, minh trang
hanh trinh » canh tranh, hanh chinh
dung cong » dung trong
cua dung » cua dang, cua dong, qua dung
cong tan » cong tac, cong san, cong thanh
tan van » tran van, tang van, luan van

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: ho ((chieu xanh) OR (chieu tinh)) - ((hanh trang) OR (hanh trinh)) cua dung cong tan van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu tinh)) - ((hanh trang) or (hanh trinh)) cua dung cong tan van ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu tinh)) - ((hanh trang) or (hanh trinh)) cua dung cong tan van ban*.
