Difficult problem.
Title: The three people A, B, and C have names Zhenzhen, Jiajia, and Zhenjia (not corresponding to who is who). Zhenzhen always tells the truth, Jiajia always lies, and Zhenjia sometimes tells the truth and sometimes lies. A person met them and asked A: 'What is B's name?' A answered: 'He is called Zhenzhen.' The person then asked B: 'Are you called Zhenzhen?' B replied: 'No, I am called Jiajia.' The person then asked C: 'What is B's real name?' C answered: 'He is called Jiajia.' Question: Can you tell who among A, B, and C is Zhenzhen, who is Jiajia, and who is Zhenjia? The answer to this question is quite surprising, so don't spend too much brain power on it.

Passing by, even elementary school students can handle this kind of question, it's just a simple reasoning...
Basically the same as asking for directions. A: True or false B: False false, C: True true (Is it like this?)
Wrong, if B is true or false, then AC must have both true values, but in ac no one says B is true or false
