Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chieu xanh » chieu sach, chieu sang, chieu tinh
hieu lang » chieu sang, hieu quang, nhieu tang
chinh ta » chinh tai, chinh va, chinh tri
ta nhung » tay nhung, va nhung, tu nhung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

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 ((hieu lang) OR (chieu xanh)) - hanh chinh ta nhung cong dan toan cao~.
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) or (chieu xanh)) - hanh chinh ta nhung cong dan toan cao*.
