Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
hanh manh » hanh mang, lanh manh, hoang manh
cua nhung » va nhung
manh cua » doanh cua, ban cua
cong dan » cong san, cong tan, cong tac
toan cao » toan ban, toan tap

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