Perhaps you should try some spelling variations:
chinh luat » chinh luan, hinh luat, trinh luat
chieu sang » chieu sach, chieu xanh, hieu lang
hieu manh » chieu xanh, hieu nganh, dieu hanh
dung cong » dung trong
hang cong » dang cong, hang nong, bang cong
dan chan » dan gian, dan ca, van chat
chan cau » phan cau, can cau, chinh cau

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 manh) OR (chieu sang)) - hanh chinh luat ((dung cong) OR (hang cong)) dan chan cau~.
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu sang)) - hanh chinh luat ((dung cong) or (hang cong)) dan chan cau*.
