Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sach » chinh sach, chiet tach, chieu sang
nhanh lang » nhanh quang, nhanh thang, nhan dang
pha nhung » phai nhuong, tham nhung, phan chung
ha nhung » hoa nhung, hay nhung, va nhung
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban

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 chieu sach - nhanh lang ((ha nhung) OR (pha nhung)) cong dan ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - nhanh lang ((ha nhung) OR (pha nhung)) cong dan ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - nhanh lang ((ha nhung) OR (pha nhung)) cong dan ((toan tai) or (toan ban))*.
