There are literally hundreds of Beijingshitaijiquan forms and variations(of such) that it would make your head spin.
When I first started out in competition (45+years ago or so
), the competitions forms were great but they got out of hand whereby if one did not do the 'cumpulsory' form (per the style i.e.Yang, Wu, Chen, or Sun)
you would be rated lower than one who followed the status quo (of known Beijing Institute form arrangement). I mentioned that at one tournament, I did Li style but since the judges were not familiar with the style. I was rated lower on X scale. I enjoyed doing the form but over the years, it did not mesh with me. Why learn Demon kungfu when demons no longer exist, at least so they tell me
I realized that my mind could only remember so many forms so I quit doing the many and stuck to the few that I still practice for memory and training
