Perhaps you should try some spelling variations:
thien chinh » tien thinh, thien chien, thi chinh
theo chinh » te chinh, che chinh, thi chinh
nhung cong » dung cong, thong cong, hang cong
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan ban » van ban
hanh va » hang va, hanh vi
han va » hang va, nhan va, ban va

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: ((theo chinh) OR (thien chinh)) sach - hanh ((han va) OR (hanh va)) nhung cong san toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chinh) or (thien chinh)) sach - hanh ((han va) OR (hanh va)) nhung cong san toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chinh) or (thien chinh)) sach - hanh ((han va) OR (hanh va)) nhung cong san toan ban*.
