Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tung » thanh cong
hoc thieu » toc thieu, hoc hien
nhung cau » chung cu, nhung bai, nhu cau
cong dan » cong san, cong dong, cong tac
cong tan » cong tac, cong san, cong thanh
tung va » trung va, tuong va, dung va

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 - thanh tung va nhung ((((cong dan) OR (huong dan))) OR (cong tan)) nhung cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh tung va nhung ((((cong dan) OR (huong dan))) or (cong tan)) nhung cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh tung va nhung ((((cong dan) OR (huong dan))) or (cong tan)) nhung cau*.
