Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh dang » hanh dong, hanh dung, hanh mang
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
anh dang » anh dong, anh dung, anh bang
cua dung » cua dang, cua dong, qua dung
cong tan » cong tac, cong san, cong thanh
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: ho chieu xanh - ((hanh dang) OR (anh dang)) cua dung cong tan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh dang) or (anh dang)) cua dung cong tan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh dang) or (anh dang)) cua dung cong tan ((toan cau) OR (toan ban))*.
