Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
trung cua » truong cua, trung tuan, trung cap
dang cong » dung cong
cua dang » cua cong, cua ban
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan tap, toan tai
toan ban » van 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 sang)) - thanh trung cua dang cong tan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - thanh trung cua dang cong tan ((toan cau) or (toan ban))*.
