Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, thien anh, thien danh
hanh tranh » canh tranh, hanh trinh, hanh trang
hieu manh » chieu xanh, hieu nganh, dieu hanh
tranh cua » doanh cua, manh cua
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than tap » toan tap, han tap, phan 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: toc ((thieu xanh) OR (hieu manh)) - hanh tranh cua dung ((cong dan) OR (cong tan)) than tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu xanh) OR (hieu manh)) - hanh tranh cua dung ((cong dan) or (cong tan)) than tap~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu xanh) OR (hieu manh)) - hanh tranh cua dung ((cong dan) or (cong tan)) than tap*.
