Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chieu sang, hieu cach
dong cong » duong cong, dung cong, dang cong
trung co » trung bo, trong co, truong cao
cong tac » cong ty
tac nhan » tao nhan, cac nhan, dac nhan
nhan cau » nhanh cau, phan cau, nhan sau
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) OR (chieu sach)))) - thanh trung co dong cong tac nhan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (((chiet tach) OR (chieu sach)))) - thanh trung co dong cong tac nhan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (((chiet tach) OR (chieu sach)))) - thanh trung co dong cong tac nhan cau*.
