Perhaps you should try some spelling variations:
hanh trinh » hanh chinh
thieu xanh » chieu xanh, thien anh, thien danh
hieu manh » chieu xanh, hieu nganh, dieu hanh
dung cong » dung trong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac
va dung » van dung, va duong, vat dung

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: hoc ((thieu xanh) OR (hieu manh)) - ((hanh trinh) OR (canh tranh)) va dung cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (hieu manh)) - ((hanh trinh) or (canh tranh)) va dung cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (hieu manh)) - ((hanh trinh) or (canh tranh)) va dung cong dan than cap*.
