Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
chau tinh » cuu tinh, ha tinh, cua tinh
doanh cua » doanh luan
cong van » cong vang, song van, cong tan
cong san » cong tac
toan cao » toan ban, toan tap

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 tinh) OR (chau tinh)) - hanh doanh cua cong ((cong van) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) OR (chau tinh)) - hanh doanh cua cong ((cong van) or (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) OR (chau tinh)) - hanh doanh cua cong ((cong van) or (cong san)) toan cao*.
