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