1. If the identification result after calling the police is indeed Li Ming’s signature, what responsibility does she need to bear?

Answer: I am responsible for repaying the arrears of 80,000 yuan, and nothing else.

2. If the IOU is true, is her accusation false?

Answer: It is not considered a false accusation.

3. If the IOU is true, does she need to pay the investigation fees after the case is filed, such as the appraisal fee?

Answer: Zhang Hong is responsible.

Question added:

So should Zhang Hong go to court to sue now or go to the Public Security Bureau to report the case? What Zhang Hong is worried about is that if the IOU turns out to be true, she will pay a greater price for suing or reporting the case, such as being fined again or even going to jail. We are both legally illiterate, so please answer in as much detail as possible, thank you.

Answer: You can report the crime to the Public Security Bureau. If the case is not reported, Zhang Hong will apply to the court for identification of the handwriting on the IOU after Wang Qiang files a lawsuit. This is just an ordinary loan dispute, and there will not be "a fine or even jail time".
