Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
dung cong » dung trong
danh qua » doanh quan, manh quan, thanh qua
hanh qua » thanh qua, hanh sua, hanh cua
cong dan » cong san, cong tan, huong dan
dan phan » doan phan, dan chan, van phan

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 ((chieu xanh) OR (chieu sach)) - canh ((danh qua) OR (hanh qua)) dung cong dan phan tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - canh ((danh qua) OR (hanh qua)) dung cong dan phan tu~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - canh ((danh qua) OR (hanh qua)) dung cong dan phan tu*.
