Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hieu manh » chieu xanh, hieu nganh, dieu hanh
dan thanh » dang thanh, danh thanh, ban thanh
thanh lap » thanh san, phan lap, thanh hai
hanh cua » manh cua, hang cua, doanh cua
hanh sua » hinh su, hanh va, hanh tu
ban hang » ngan hang
hang dan » hang dau, hang ban, tang dan

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 sach)) - hoang ((hanh cua) OR (hanh sua)) ban hang dan thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu sach)) - hoang ((hanh cua) OR (hanh sua)) ban hang dan thanh lap~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu sach)) - hoang ((hanh cua) OR (hanh sua)) ban hang dan thanh lap*.
