Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chiet tach » chieu sach
cua nhung » va nhung
manh toan » thanh toan, anh tuan, tinh toan
ho chiet » ho chieu, ho thiet, hoc thiet
canh ban » can ban, canh dan, canh van
dan chan » dan gian, dan ca, van chat
ban cua » ban quan

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: ho chiet tach - canh ban cua nhung cong ((manh toan) OR (dan chan)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - canh ban cua nhung cong ((manh toan) or (dan chan)) cau*.
