When one states that teachers have changed the way they do the form, it's sometimes due to faulty perception and limited understanding of the form
This is rarely the case in itself but both sides acknowledging (per the teacher) the student cannot do the posture but I (teacher, usually) can adjust it to match his physical conditioning of the syudent i.e. his aqbility or lack to
mimic the posture hiw it was intended. Secondly, Just as Yang Luchan learnt Chen Family System, he adjusted/changed crtain postures according to his experience and understanding as a way to highlight his own
previous martial background while integrating elements of what he learnt from Chen style.
I remember that when my teacher was showing us the right and left sides of a form routine (modern insight
) 1/2 the class would not show up so he stopped doing that.
NOTE: We mostly did the Beijing24shitaijiquan but it was also useful for "traditional" routines
This problem also occurs when teachers teach the form before they've mastered it themselves.
Not necessarily keeping in mind that since Chen Family Style (Chenjiagou) was the template of learning/instruction, all who learnt the tem[plate made explicit conscious choices to embellish/prioritize
their own view and add to this template while creating their own system and imprint, hence Yang style, Wu style(s), Sun style, etc
Sometimes when a student observes others doing taiji and their postures seem different, it's the student's fault.
There is no fault if the student is doing x form in x manner, at least, there shouldn't be! If the student understands he needs correction then he realizes his deficiency so he corrects himself/herself accordingly.
