Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh tra, thanh tuan
thanh toan » thanh hoa, thanh san, tinh toan
tranh vat » trinh vat, tranh va, tranh van
dung cong » dung trong
theo dat » theo dau, theo luat, tren dat
dat sach » mat sach, dat khach, nam sach
vat dung » van dung, va dung, viet dung

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo dat sach - canh tranh vat dung cong ((thanh tran) OR (thanh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo dat sach - canh tranh vat dung cong ((thanh tran) OR (thanh toan)) cau*.
