Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tran » thanh trang, thanh tra, thanh tuan
thanh toan » thanh hoa, thanh san, tinh toan
van nhuong » van chuong, van phuong, van huong
hoc thieu » toc thieu, hoc hien
van phung » van phong, van hung, van chuong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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: hoc thieu xanh - ((thanh tran) OR (thanh toan)) ((van phung) OR (van nhuong)) cong dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((thanh tran) OR (thanh toan)) ((van phung) or (van nhuong)) cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((thanh tran) OR (thanh toan)) ((van phung) or (van nhuong)) cong dan than cao*.
