Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhanh dong » hanh dong, nhanh chong, anh dong
doi chieu » doc hieu, doi chi, ho chieu
chung dan » chung han, hung dan, chung nhan
qua dung » quang dung, qua song, qua cong
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: doi chieu xanh - nhanh dong ((qua dung) OR (su dung)) chung dan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - nhanh dong ((qua dung) OR (su dung)) chung dan ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - nhanh dong ((qua dung) OR (su dung)) chung dan ((toan cau) or (toan ban))*.
