Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san, tinh toan
tuan trong » thuan trong, quan trong, tran trong
doc trieu » dong trieu, toc thieu, doc hieu
thanh tra » thanh hoa
cong tan » cong tac, cong san, cong thanh
tan can » toan can, tan van, ban can
can cau » van cau, ban cau, ca cau

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: "doc trieu tinh - ((thanh tra) OR (thanh toan)) tuan trong cong tan can cau~".
• Adding a wildcard symbol may retrieve word variants: doc trieu tinh - ((thanh tra) OR (thanh toan)) tuan trong cong tan can cau*.
