sorry since this is cma thread, when i stated “every style” i assumed you would understand that i was implying chinese, not on the universal.
although xing yi at the novice stage does concentrate on the external, this is only to teach the player, proper and correct body allignment and movement.
however the internal starts immediatly even at novice level from the “santi”, which is the first posture learnt and usually studied before even taking the first step towards the “elements”
at the comencment of xingyi, those i have trained with always do santi, for as long as they can, before starting other practices.
the concepts of wuji, taiji and liangyi to santi, are all internal and although the player may not fully understand these principles initially, they are most certainly there from the start.
xing yi uses many ging, but the main focus is on “paan ging” (whole body power)
in “siulumtao”, the internal is also evident, however from my experiance, xing yi study is always on the internal aspects.
one cannot deny the physical representation of the elements and animal movements from the external, however from santi, the “six internals/eight methods” are also prevelent even at the early stages.
as i said before there are many xing yi all doing something different, some have animals 10 - 12, some have just elements, some even just do santi.
others have there stances on different weight levels, 50/50, 40/60 and 60/40.
do you know which xing yi you learnt = daixingyi, liuhubafaxingyi, heibeixingyi, sanxixyingyi,pichuanxinhyi saanxixyingyi??? .
if you know which one it may help to explain your question on the simularities you have seen
