Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh toan » thanh hoa, thanh san, tinh toan
hien hanh » dieu hanh
dung cong » dung trong
tac tieng » tap tieng, tay tieng, toan tieng
toan tan » toan tang, toan tran, toan ban
tan dung » tran dung, tin dung, van dung
ta tieng » tap tieng, tu tieng, va tieng

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 ((chieu xanh) OR (hien hanh)) - thanh toan tan dung cong ((tac tieng) OR (ta tieng)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (hien hanh)) - thanh toan tan dung cong ((tac tieng) OR (ta tieng)) tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (hien hanh)) - thanh toan tan dung cong ((tac tieng) OR (ta tieng)) tap*.
