Perhaps you should try some spelling variations:
thanh trung » thanh tung
xuan truong » xa truong, duong truong
doi chieu » doc hieu, ho chieu, mot chieu
cua thong » cua thuong, cua khong, cua tong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac
doi chi » doi khi

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: ((doi chieu) OR (doi chi)) sach - thanh trung ((cua thong) OR (xuan truong)) cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doi chi)) sach - thanh trung ((cua thong) or (xuan truong)) cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (doi chi)) sach - thanh trung ((cua thong) or (xuan truong)) cong dan than cap*.
