Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
doi chieu » doc hieu, doi chi, ho chieu
minh tuan » anh tuan
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
van dang » van dung, van nang, van dan
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 - ((minh tuan) OR (canh tranh)) ((van dang) OR (van dong)) cong manh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - ((minh tuan) or (canh tranh)) ((van dang) OR (van dong)) cong manh toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - ((minh tuan) or (canh tranh)) ((van dang) OR (van dong)) cong manh toan ban*.
