Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh luan » doanh nhan
luan hung » luan chung, lan hung, luan ung
thanh cau » thanh chau, thanh mau, nhanh cau
ho chieu » theo chieu, hoc thieu, doi chieu
cong ban » cong bang, cong tan, cong dan
cong san » cong tac

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: "ho chieu tinh - hanh doanh luan hung ((cong ban) OR (cong san)) thanh cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh doanh luan hung ((cong ban) OR (cong san)) thanh cau*.
