Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
chi sach » chinh sach, chieu sach, co sach
mang cua » manh cua, dung cua, ban cua
dan than » dan chan, ban than, van than
doi chi » doi khi

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 sach - hanh mang cua nhung cong ((xuan toan) OR (dan than)) tap~.
• Adding a wildcard symbol may retrieve word variants: doi chi sach - hanh mang cua nhung cong ((xuan toan) or (dan than)) tap*.
