Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chieu sang, hieu cach
thanh tung » thanh cong
tuan thong » toan thong, tran thong, tuan phong
thong cong » trong cong, tong cong, thong thong
tung tuan » trung tuan, hung tuan, quang tuan
cong san » cong tac
san than » sang than, san thanh, ban than
than cao » toan cao, thai cao, than cap

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: theo ((((chieu xanh) OR (chieu sach))) OR (chiet tach)) - thanh tung tuan thong cong san than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chieu xanh) OR (chieu sach))) or (chiet tach)) - thanh tung tuan thong cong san than cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu xanh) OR (chieu sach))) or (chiet tach)) - thanh tung tuan thong cong san than cao*.
