Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thanh toan » thanh hoa, thanh san, tinh toan
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
chi danh » chi dan, chi anh, chi dinh
mang cua » manh cua, dung cua, ban cua
dan toan » van toan, dan than, manh toan

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: doi ((chi danh) OR (chi nhanh)) - hanh mang cua nhung cong ((dan toan) OR (thanh toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: doi ((chi danh) or (chi nhanh)) - hanh mang cua nhung cong ((dan toan) or (thanh toan)) cao*.
