For the purpose of this thread, I am Going to upload Shi De Yang's version of Da Luohan for the purpose of observing it in correlation to Shi De Ci and Shi De Jun's version, and my theory on why theres a Jintong Luohan Quan AND Da Luohan Quan, along with Xiao Luohan and Luohan Shibashou, and share the aligning movements.
This is just my observation from practice, excluding the encyclopedia.
