Perhaps you should try some spelling variations:
thanh truong » thanh trung, thanh thuong, thanh tung
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
truong vat » truong va, truong van, trong vat
dung cong » dung trong
vat dung » van dung, va dung, viet dung
cong tap » cuong tap, cong tac, cong tan
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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 sach)) - thanh truong vat dung cong tap ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - thanh truong vat dung cong tap ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - thanh truong vat dung cong tap ((toan cau) OR (toan tap))*.
