Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu tinh » trieu tinh, lieu tinh, chau tinh
chiet tach » chieu sach
dai luong » dai cuong, dai duong, hai duong
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 ((chieu tinh) OR (chiet tach)) - thanh trung ((dai luong) OR (do luong)) cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (chiet tach)) - thanh trung ((dai luong) OR (do luong)) cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (chiet tach)) - thanh trung ((dai luong) OR (do luong)) cong dan than cap*.
