Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
hanh dung » thanh dung, hanh dong, manh dung
ho chieu » theo chieu, hoc thieu, doi chieu
anh dung » anh dong, anh huong, sach dung
cong dan » cong san, cong tan, huong dan
toan ban » van ban
toan cao » toan 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: ho chieu xanh - ((hanh dung) OR (anh dung)) va nhung cong dan ((toan ban) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh dung) OR (anh dung)) va nhung cong dan ((toan ban) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh dung) OR (anh dung)) va nhung cong dan ((toan ban) or (toan cao))*.
