Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh dung » thanh dung, anh dung, hanh dong
chu sach » thu sach, chieu sach, chuc hach
cau sach » cao sach, hau sach, rau sach
cong tac » cong ty
tac than » tac thanh, tam than, tac nhan
than cau » toan cau, phan cau, than cap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu sach) OR (cau sach)) - hanh dung va nhung cong tac than cau~".
• Adding a wildcard symbol may retrieve word variants: chao ((chu sach) OR (cau sach)) - hanh dung va nhung cong tac than cau*.
