Old into new

In tai chi, there may be a better way to do a move or technique that is not necessarily right or wrong. There are many methods to achieve similar outcomes. What is more important to me as an instructor is that a learner do something different than what they normally default to in their movements. If anything is the correct step, that is. Whether the teacher says do this or do that is important particularly inasmuch as it helps the student change old patterns of movement into new. Beginners should think about this.
