Perhaps you should try some spelling variations:
luan thong » luan phong, luan tuong, luat thong
chieu xanh » chieu sach, chieu sang, chieu tinh
thong cong » trong cong, tong cong, thong thong
hanh dong » anh dong
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
nhan tai » hang tai, van tai, toan tai
toan tap » toan ban
ha dong » hoat dong, van dong

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 - ((hanh dong) OR (ha dong)) luan thong cong dan ((nhan tai) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh dong) OR (ha dong)) luan thong cong dan ((nhan tai) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh dong) OR (ha dong)) luan thong cong dan ((nhan tai) or (toan tap))*.
