Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hieu xanh » hieu manh, hieu nganh, dieu hanh
dong cong » duong cong, dung cong, dang cong
cong cua » cong cu, dong cua, huong cua
cua dong » chua dong, cua cong, cua dang
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cap » khan cap, thanh lap, thanh cac

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) OR (chieu xanh)) - thanh cong cua dong cong tan than cap~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu xanh) OR (chieu xanh)) - thanh cong cua dong cong tan than cap*.
