Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
tranh cua » doanh cua, manh cua
cua khong » hua khong, cua phuong, cua thuong
ho chieu » theo chieu, hoc thieu, doi chieu
tong tap » tuong tac, trong tan, tong hop
cong tac » cong ty
toan tap » 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: ho chieu tinh - canh tranh cua khong ((tong tap) OR (cong tac)) toan tap~.
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - canh tranh cua khong ((tong tap) or (cong tac)) toan tap*.
