A company held a literature and art show  There were four groups of programs  Xiao Wang, Xiao Zhang, Xiao Zhao and Xiao Li drew lots to decide the performance sequence  Xiao Li at the front desk asked them who came first and who came later  Xiao Wang said, I'm the first to go on stage  Xiao Zhang said, I'm the third  Xiao Zhao said, I'm the fourth
Xiao Li said, anyway, I'm not the last
No matter who told a lie, the performance sequence of the four people can be inferred.
