Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tuan
tieu sach » chieu sach, dien sach, te sach
thanh tra » thanh toan, thanh hoa
xuan hung » xuan huong, xuan chung, luan hung
cong san » cong tac
cong tan » cong tac, cong thanh, cong ty
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 tieu sach - ((thanh tran) OR (thanh tra)) xuan hung ((cong san) OR (cong tan)) than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - ((thanh tran) OR (thanh tra)) xuan hung ((cong san) or (cong tan)) than cap~".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - ((thanh tran) OR (thanh tra)) xuan hung ((cong san) or (cong tan)) than cap*.
