Perhaps you should try some spelling variations:
theo chiet » theo chieu, thep thiet
chiet tach » chieu sach
tong cong » trong cong, cong cong, dung cong
hanh ban » thanh ban, hanh san, hanh han
hang ban » hang luan, hang va, hang tai
cua tong » cua cong, cua dong, cua nong
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan 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 chiet tach - ((hanh ban) OR (hang ban)) cua tong cong dan ((toan tai) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chiet tach - ((hanh ban) OR (hang ban)) cua tong cong dan ((toan tai) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chiet tach - ((hanh ban) OR (hang ban)) cua tong cong dan ((toan tai) or (van ban))*.
