Perhaps you should try some spelling variations:
trinh tinh » trinh kinh, trinh dinh, trinh sinh
nhanh tinh » nhanh thanh, hanh trinh, nhan sinh
trinh tin » trinh kinh, trinh toan, trinh tu
tinh cua » trinh cua, sinh cua, tinh chat
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
than cau » toan cau, phan cau, than cap

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: doi ((trinh tinh) OR (trinh tin)) - nhanh tinh cua cong ((cong tan) OR (cong tac)) than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((trinh tinh) or (trinh tin)) - nhanh tinh cua cong ((cong tan) OR (cong tac)) than cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((trinh tinh) or (trinh tin)) - nhanh tinh cua cong ((cong tan) OR (cong tac)) than cau*.
