In hunting for truely working Qi gong practise.
As people decide to leave bits out or replace them with their favorites or own theories, they deform Qi gong. They water down it.
First through likes, and dislikes, and preferences, secondly through ignorance, thirdly own intentions. 
The results is a mixture of something completely different, that it was originally.
+ Method to prepare the body, the workshop. When it is filled with discomfort, people will replace it with more pleasurable concepts or practises, wishing or imagining the same result.
+ The time being spent with qi gong practise stages. Nowadays it is out of reality, no where near where the founders were, when they practised. All because many believe they are exceptional talents.
The time is needed to spend with certain stages in reality would suprise many. Current day and age dictate differently. The way we wish or imagine how Qi gong works, is far from its reality and true methods.
“What is difficult is the perseverance. It took me ten years to discover my chi, but thirty years to learn how to use it.”
― Ma Yueh Liang ( search him, who he was and see how important this saying is. )
+ In the age of 3 month Qi gong teacher courses, from zero, and beginner qi gong courses with the promise of microcosmic orbit excercises it is very difficult to stand sober and decent and accept the true nature of qi gong processes. Why would they, if the promises say differently.
Sarlatans are trading sensations, as if it is Qi , meanwhile they themselves have no Qi either and never cultivated it truely. No wonder there is confusion. What is to show there, except talk?
Rather do this for a long time:
+ Regulate lifestyle, emotions
+ Strengthen Kidney | Jing
+ Accumulate Qi in lower Dantian 
Certain excercises or qualities takes years, doesnt matter how else we imagine. Sensations, and experiences are over rated in this matter, moreover confusing in the process. Qi cultivation requires to access Qi and false sensations will only lead many astray.
