Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thanh tung » thanh cong
cap dung » ap dung, cao dung, chan dung
cong san » cong tac
san tran » tan tran, ban tran, dang tran
tran cau » tran chau, toan cau, ran cau

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) OR (chieu sang)) - thanh tung ((cap dung) OR (cao dang)) cong san tran cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - thanh tung ((cap dung) or (cao dang)) cong san tran cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - thanh tung ((cap dung) or (cao dang)) cong san tran cau*.
