Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
doanh cua » doanh luan
thanh cac » hanh cac, thanh bac, thanh ca
manh cua » ban cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh

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