First, it is not illegal to brag. 1 Li Bai is bragging. Li Bai is a romantic poet, and exaggeration is one of his usual methods, so the purpose of Li Bai's writing this poem is to show others how brave he was, even killing people. However, since this matter is false, Li Bai will certainly not be punished. After all, bragging is not even prohibited by law, and I don't know how many cows are boasted in Li Bai's poems. If you really broke the law, then Li Bai doesn't know how many times he has died.
There is also a saying that Li Bai met with Amnesty at that time. It is certain that Li Bai met an amnesty in his life, because it is easy for the Tang Dynasty to like all kinds of amnesties, and it is indeed possible for the Tang Dynasty to release this kind of thing, because according to the time, what Li Bai may encounter when he was young is not an ordinary amnesty, but the reign of Emperor Xuanzong of the Tang Dynasty, Li Longji. In this case, except for the rebels, the prison is basically empty, but did Li Bai encounter Amnesty when he killed people?
Third, Li Bai, a criminal with possession, finally said that Li Bai was hiding. As for the hiding place, it is a temple, and the temple is indeed a very suitable place, because at that time, officers and men could not search and wipe the temple at will, and the temple was basically the private property of monks or Taoist priests at that time, so if Li Bai had a good relationship with one of them, then the temple was the best hiding place for the murderer Li Bai.
