Some of Zhao, Qian, Sun and Li won the special prize in the latest lottery. I know now that Zhao can win the special prize only if he plays at the A betting station. If Qian wins the special prize, the lottery must be held after 10:00. The lottery started at 8: 30 a.m. and lasted only 20 minutes, and the lottery number is self-made.
 Sun or Li won the special prize can be inferred based on this.
