How do slang lawyers know the real list?

The list of slang lawyers was given by real rats in prison. He kept a close eye on Piao Chang-hao's every move. In order to ensure his safety and let him continue to play the role of a mouse, I gave him the real list. The way to give it to him is this: Piao Chang-hao really wanted to take Cui Dao and the list he gave him, but suddenly someone came and knocked himself out. When he woke up, he found that the note in the bag had changed. All the lists are written on the tarot cards.
