Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
thanh toan » thanh hoa, thanh san, tinh toan
tuan trong » thuan trong, quan trong, tran trong
hoc thieu » toc thieu, hoc hien
thanh tra » thanh hoa
cong tan » cong tac, cong san, cong thanh
tan chan » dan chan, ban chan, can chan
chan cau » phan cau, can cau, chinh 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: "hoc thieu tinh - ((thanh tra) OR (thanh toan)) tuan trong cong tan chan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - ((thanh tra) OR (thanh toan)) tuan trong cong tan chan cau*.
