Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hanh trang » thanh trung, hanh trinh, minh trang
hoc thieu » toc thieu, hoc hien
van cong » van dong, van phong, phan cong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban
cua van » cua ban, cua vat, cua dan

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 trang) OR (canh tranh))) OR (hanh chinh)) cua van cong dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((((hanh trang) OR (canh tranh))) or (hanh chinh)) cua van cong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((((hanh trang) OR (canh tranh))) or (hanh chinh)) cua van cong dan toan ban*.
