How did Dan Tianfang remember it?
Dan Tianfang's grandparents and parents are storytellers, which can be said to be a storytelling family. So, first of all, he has listened to many storytellers since he was a child. Naturally, he remembers a lot. I like telling stories very much, and I don't remember them, but I can also describe a military commander without thinking, because there are only a few words, such as the eight-character knife-shaped eyebrows sticking up to the sky, straight into the temple, leopard eyes and big mouth.
There was a master in Dan Tianfang. The master told him what to say and told stories in storytelling language. After n years, it has become a habit, so there is no need to recite the manuscript.
Most storytellers remember the buttons and baggage of books. There is no need to remember this language. They all came with their mouths open.
