As is the case in other fields, to learn a culture and enjoy its benefits, there must first be learning obtained from an expert of that culture. Here, the disposition and proper grounding of the expert or teacher is very important. Since there would be no criteria for judgment when first stepping into a new culture to ask for teaching, and even instructions from incorrect methods will also be accepted without discrimination. If the wrong culture were to be learned as nothing more than a light hobby, then it would be no more than a waste of time and money, but to learn in a distorted method a culture which deals with the health and mind of people, and invest time for adoption by mind and body, it can really become a serious evil. Therefore, in order to serve as a leader of a culture one must first be equipped with commensurate ability. And even if a certain amount of ability were to be possessed, there should also be a humble attitude for knowledge, and depth as yet unknown, to continue in training without ceasing, and requires the ethics to restrain from mystifying teaching which is not yet understood, to make the world dizzy and fool the people, with worldly opportunistic appeal for using distorted learning, for the sake of personal gain and profit.

In order to prevent damage from people who are not qualified to be leaders, the well established culture will approach the people with a publicly certified system equipped with capacity for self purification. Regrettably, the Daoyin culture to benefit people for health is yet to be outfitted with such an authentication system designed for the modern structure. It would behoove those who wish to learn mind & body training art such as Daoyin to be discriminating in their selection of Daoyin expert, to prevent loss.

In Daoyin, those who are not duly qualified as teachers and thus have not resolved the basic problem of Daoyin, yet teach others, would generally exhibit the following characteristics.

Insist overly so on the teacher student relationship, and thereby claim that he himself is the only person with authenticity.
What is important is competence. For a chef to dole out tasteless food while claiming his teacher to be great has no meaning.

During training instruction, insists overly so on a repetition of movement. Says something vague, like keep doing it over & over and some day it will all come together.
This is the banal method of unqualified teachers. Certainly repetition is very important. But to go along without knowing direction and results can result in an irrelevant direction. Once a movement has been mastered, subsequent training methods should be presented.

Intentionally ignores the inner workings of Qi, coordinated effect of three body parts(arms, legs, torso), yin & yang transformation and other traditional training methods, and will not tolerate mentioning them.
Since unable to explain it, forbids speaking about it. Goes so far as to attack those who ask many questions as having a bad attitude for learning.

Cannot explain specific angles and shapes of each movement, and the positioning of arms and legs.
This is where the real ability for Daoyin is specifically exposed. Teachers should by all means be able to explain in detail.

Even for movements which by themselves change little by little, requires their shape of motion to be followed exactly.
When they themselves become the standard, then all others who are learning are wrong. Then they can own the sole position to say, it is wrong.

Conversely, Daoyin experts who are continuing in the tradition of Daoyin must be able to perform the following.

Are so familiar with Daoyin itself, to possess the ability to interpret motion and contents.
Must be able to correct the exact angle and position, and explain the effects of each motion.
Must fully understand the coordinated effect of three body parts as the way of understanding of inner energy working.
When necessary, must be able to apply the movement as appropriate for each personal situation.
