Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
quan trong » gian trong
hanh tang » hanh trang, anh tang, hanh mang
tang quan » tang luan, nang quan, tong quan
thanh tap » thanh lap, thanh tay, thanh tam
thanh tai » thanh hai, thanh toan, doanh tai
cong ban » cong bang, cong san, cong tan

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)) - hanh tang quan trong cong ban ((thanh tap) OR (thanh tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - hanh tang quan trong cong ban ((thanh tap) OR (thanh tai))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - hanh tang quan trong cong ban ((thanh tap) OR (thanh tai))*.
