Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » ho chieu, theo chu, thi chieu
nhung cong » dung cong, thong cong, hang cong
thanh toan » thanh hoa, thanh san, tinh toan
trung cua » truong cua, trung tuan, trung cap
dang cong » dung cong
toan ban » van ban

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 chieu) OR (theo tieu)) xanh - thanh trung cua ((nhung cong) OR (dang cong)) thanh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo tieu)) xanh - thanh trung cua ((nhung cong) or (dang cong)) thanh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo tieu)) xanh - thanh trung cua ((nhung cong) or (dang cong)) thanh toan ban*.
