Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
manh trung » manh tung, thanh trung, manh hung
trung tuan » trung thanh, trung tam, tran tuan
tuan hang » tuan hoang, tuan bang, tuan dang
hang cong » dang cong, hang nong, bang cong
danh toan » anh toan, dan toan, dang toan
manh toan » thanh toan, anh tuan, tinh toan

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: hoc ((chieu xanh) OR (chieu sang)) - manh trung tuan hang cong ((danh toan) OR (manh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sang)) - manh trung tuan hang cong ((danh toan) OR (manh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu sang)) - manh trung tuan hang cong ((danh toan) OR (manh toan)) cau*.
