Perhaps you should try some spelling variations:
theo chiet » theo chieu, thep thiet
chiet tach » chieu sach
canh trinh » canh tranh, hanh trinh, canh tinh
trinh van » trinh han, trinh quan, trinh toan
van lang » van nang, va lang, van hang
cong dan » cong san, cong tan, cong dong
toan tap » toan ban

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chiet tach - canh trinh van lang ((cong dan) OR (huong dan)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo chiet tach - canh trinh van lang ((cong dan) OR (huong dan)) toan tap*.
