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
dong cong » duong cong, dung cong, dang cong
tung cua » trung cua, tuong cua, dung cua
cua dong » chua dong, cua cong, cua dang
tan than » tan thanh, ban than, tam than

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) OR (chieu sang)) - thanh tung cua dong cong ((tan than) OR (tan tran)) cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sang)) - thanh tung cua dong cong ((tan than) or (tan tran)) cap~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) OR (chieu sang)) - thanh tung cua dong cong ((tan than) or (tan tran)) cap*.
