Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
doi chieu » doc hieu, doi chi, ho chieu
tranh cua » doanh cua, manh cua
cua khong » hua khong, cua phuong, cua thuong
trung dai » truong dai, truong dao, trung tam
tung dan » dung dan, huong dan, dung dat
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 - canh tranh cua khong ((tung dan) OR (trung dai)) ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - canh tranh cua khong ((tung dan) OR (trung dai)) ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - canh tranh cua khong ((tung dan) OR (trung dai)) ((toan cau) or (toan ban))*.
