88. After the mid-term exam, Xiaojun and Xiaonan made guesses about the rankings of five classmates in the class.

Xiaojun's guess: Xiaojun first, Xixi second, Xiaohua third, Xiaoguang fourth, Xiaonan fifth;
Xiaonan's guess: Xiaohua first, Xiaoguang second, Xixi third, Xiaonan fourth, Xiaojun fifth.
Around "Children's Day," the exam results came out. In fact, none of Xiaojun's guesses were correct, not only did he not guess any of the rankings right, but none of them were off by just one rank. Xiaonan guessed one person's ranking correctly. So what are the actual rankings of the five people?
Reference answer: Xiao Nan first place, Xiao Guang second place, Xiao Jun third place, Xi Xi fourth place, Xiao Hua fifth place
