Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
luan chung » luan chinh
hoc thieu » toc thieu, hoc hien
anh hung » anh huong, manh hung, anh dung
luan ung » luan hung, luon ung, luan luong
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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 - anh hung ((luan ung) OR (luan chung)) cong dan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - anh hung ((luan ung) or (luan chung)) cong dan ((toan cau) or (toan ban))*.
