Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
chiet tach » chieu sach
dong cong » duong cong, dung cong, dang cong
trung co » trung bo, trong co, truong cao
cong tac » cong ty
nhan cau » nhanh cau, phan cau, nhin cau
nhan sau » nhan su, nhan san, nhanh cau
co dong » o dong, cong dong, lao dong

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 (chiet tach)) - thanh trung co dong cong tac ((nhan cau) OR (nhan sau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chiet tach)) - thanh trung co dong cong tac ((nhan cau) OR (nhan sau))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chiet tach)) - thanh trung co dong cong tac ((nhan cau) OR (nhan sau))*.
