Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
chau tinh » cuu tinh, ha tinh, cua tinh
hanh dinh » thanh dinh, hinh dinh, hanh tinh
dinh thi » dinh tri
thi nang » thi cong, ki nang, thi hanh
cong dan » cong tan, huong dan, cong dong
cong san » cong tac

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu tinh) OR (chau tinh)) - hanh dinh thi nang ((cong dan) or (cong san)) thanh san~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (chau tinh)) - hanh dinh thi nang ((cong dan) OR (cong san)) thanh san*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) OR (chau tinh)) - hanh dinh thi nang ((cong dan) or (cong san)) thanh san*".
