Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
doanh cua » doanh luan
dong cong » duong cong, dung cong, dang cong
dan thanh » dang thanh, danh thanh, ban thanh
manh cua » ban cua
cong dan » cong san, cong tan, huong dan
thanh ca » thanh cha, thanh cac, thanh ha

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: hoc ((thieu xanh) OR (chieu xanh)) - hanh ((manh cua) OR (doanh cua)) dong cong dan thanh ca~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - hanh ((manh cua) or (doanh cua)) dong cong dan thanh ca~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - hanh ((manh cua) or (doanh cua)) dong cong dan thanh ca*.
