Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung don
chieu sach » chinh sach, chiet tach, chieu sang
chinh cua » chinh ca, chinh sua, hinh cua
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
tan toan » tan tran, tap toan, van toan
toan tap » toan ban

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 chieu sach - hanh ((chinh cua) OR (hinh su)) ((nhung cong) OR (dung cong)) tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((chinh cua) or (hinh su)) ((nhung cong) OR (dung cong)) tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((chinh cua) or (hinh su)) ((nhung cong) OR (dung cong)) tan toan tap*.
