Perhaps you should try some spelling variations:
trung thanh » truong thanh
chiet tach » chieu sach
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tran » trung tuan, trung tam, hung tran
hung cong » nhung cong, hung cuong, phung cong
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: theo ((chiet tach) OR (chieu xanh)) - thanh ((trung tran) OR (trung thanh)) hung cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chiet tach) or (chieu xanh)) - thanh ((trung tran) OR (trung thanh)) hung cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chiet tach) or (chieu xanh)) - thanh ((trung tran) OR (trung thanh)) hung cong dan than cap*.
