Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
chiet tach » chieu sach
hieu cach » hieu cac, chieu sach, hieu ca
trung cua » truong cua, trung tuan, trung cap
dung cong » dung trong
cua dung » cua dang, cua dong, qua dung
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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 ((((hieu cach) OR (chieu xanh))) OR (chiet tach)) - thanh trung cua dung cong dan than cap~.
• Adding a wildcard symbol may retrieve word variants: ho ((((hieu cach) or (chieu xanh))) or (chiet tach)) - thanh trung cua dung cong dan than cap*.
