Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
nhung cong » dung cong, thong cong, hang cong
hoc chieu » hoc thieu, ho chieu, hoc hien
chinh cua » chinh ca, chinh sua, chinh luan
hinh cua » sinh cua, tinh cua, dinh cua
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan ban » van 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: hoc chieu sach - hanh ((((hinh cua) OR (chinh cua))) OR (hinh su)) nhung cong tan toan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc chieu sach - hanh ((((hinh cua) or (chinh cua))) or (hinh su)) nhung cong tan toan ban*.
