Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thong cong » trong cong, tong cong, thong thong
tang luan » dung luan
chu xanh » chu manh, chua xang, chuc danh
tang cua » mang cua, hang cua, thong cua
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than ban » thanh ban, toan ban, than man

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: cho ((chu xanh) OR (chieu xanh)) - hanh ((tang cua) OR (tang luan)) thong cong dan than ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) OR (chieu xanh)) - hanh ((tang cua) or (tang luan)) thong cong dan than ban~".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) OR (chieu xanh)) - hanh ((tang cua) or (tang luan)) thong cong dan than ban*.
