Perhaps you should try some spelling variations:

chieu sach » chinh sach, chiet tach, chieu sang
hieu manh » chieu xanh, hieu nganh, dieu hanh
chong van » thong van, hong van, phong van
van thanh » ban thanh, van tuan
thanh cau » thanh chau, thanh mau, nhanh cau
trinh va » trinh van, trinh vat, trinh vi
trinh ve » trinh he, trinh vi, trinh viet

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: theo ((hieu manh) OR (chieu sach)) - hanh ((trinh va) OR (trinh ve)) nhung chong van thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu manh) or (chieu sach)) - hanh ((trinh va) OR (trinh ve)) nhung chong van thanh cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu manh) or (chieu sach)) - hanh ((trinh va) OR (trinh ve)) nhung chong van thanh cau*.
