Several students from a certain class talked about where they were going during the summer vacation this year  A said, if Zhao Ming hadn't gone to Tibet, he would have gone to Shanghai  B said, Qian Ling went to Nanjing  C said, if Lin Qun didn't go to Xining, then Zhang Hong would go to Hangzhou  Zhao Ming did not go to Tibet, nor did he go to Shanghai, D said   Qian Ling went to Guangzhou, said Wu   Ji said, Zhang Hong didn't go to Hangzhou
With hindsight, it was learned that what two people said in this discussion did not tally with the facts
Zhao Ming didn't go to Shanghai, but Lin Qun went to Xining
