Perhaps you should try some spelling variations:
hanh trung » thanh trung, hanh trang, manh trung
chieu xanh » chieu sach, chieu sang, chieu tinh
hieu manh » hieu nganh, dieu hanh, hien hanh
dung cong » dung trong
trung ap » trung cap, trung lap, trung tam
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac
ap dung » xay dung, van 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: doc ((chieu xanh) OR (hieu manh)) - hanh trung ap dung cong dan than cap~.
• Adding a wildcard symbol may retrieve word variants: doc ((chieu xanh) or (hieu manh)) - hanh trung ap dung cong dan than cap*.
