Teacher Ma Jie is very famous.
132 style used to be a single-line inheritance, and it was not until Master Meng Xiaofeng's generation that disciples were widely accepted.
Even in the Republic of China, Li Shifu and Lin Jing only passed on Master Meng Xiaofeng.
As for the style of 132, it's well practiced. I guess it depends on Meng Shizhen's biography!
You can look at the two versions of 132 Wudang Sword Book (Wudang Sword and Six Original Wudang Swords). It seems that the pictures and texts on it are all made by one person, so I have this inference (purely personal opinion, inference, no factual basis).
