In the afternoon when Li Ang returned home, the first thing he did was to study the "Yijin Jing."
The fame of this martial art could be said to surpass all those he had learned before, combined.
Its popularity primarily stems from depictions in film and television.
In a variety of movies, TV shows, and martial arts novels, "Yijin Jing" is often portrayed as a top-tier martial art.
However, in reality, the prevalence of "Yijin Jing" is not very high, one might even say it's quite low.
Compared to similar exercises like "Baduanjin" and "Bubu Jingang Gong," far fewer people practice "Yijin Jing."
The reason for this is not complex—it's because "Yijin Jing" is too complicated.
For something to become widely adopted, it must be sufficiently simple, optimally without any barriers to entry.
"Yijin Jing" is divided into two types of exercises: the internal and the external, each consisting of twelve movements.
