Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung don
hanh dung » thanh dung, anh dung, hanh dong
dung cong » dung trong
chao chu » cho chu, cua chu, cao cho
chu sach » cau sach, thu sach, chieu sach
than cau » toan cau, than cap, thanh chau
phan cau » phan dau, phan cac, phan tu

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