Perhaps you should try some spelling variations:
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
chau tinh » cuu tinh, ha tinh, cac tinh
cua tinh » cua sinh, va tinh, ha tinh
chinh ta » chinh tai, chinh va, chinh tri
dan toan » van toan, dan than, manh 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: ho ((chau tinh) OR (cua tinh)) - hanh chinh ta ((nhung cong) OR (thong cong)) dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) or (cua tinh)) - hanh chinh ta ((nhung cong) OR (thong cong)) dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chau tinh) or (cua tinh)) - hanh chinh ta ((nhung cong) OR (thong cong)) dan toan ban*.
