There are two views. First, Li Bai thinks that the spectacular is not enough to describe the hanging temple, but a little more spectacular, so he deliberately added a little. First, Li Bai was drunk and ordered a little more. When he woke up, he deliberately said that he was a little more spectacular than the Hanging Temple!
Personally, I think the first one is more credible, because Li Bai has never written typos elsewhere.
