Taijiquan Large Frame Practice

The Marvel of Human Structure: For example, when practicing Taijiquan, if the angle and position of the upper arm and body are correct, it results in sinking the shoulders and dropping the elbows. Yet, many people still do it incorrectly. The teacher uses the large frame to teach Yang-style Taijiquan.
Taijiquan Large Frame Practice: Use the elbow to lead the shoulder. From an anatomical perspective, why does lifting the elbow allow the shoulder to naturally relax and sink?
