Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
hanh tang » hanh trang, anh tang, hanh mang
thanh cac » hanh cac, thanh bac, thanh ca
tang cua » mang cua, hang cua, tang luan
cong van » cong vang, song van, cong tan
cong san » cong tac

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)) - hanh tang cua ban ((cong van) OR (cong san)) thanh cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - hanh tang cua ban ((cong van) OR (cong san)) thanh cac~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - hanh tang cua ban ((cong van) OR (cong san)) thanh cac*.
