Here’s a “hip” tip. In 80% of the Yang-Style Short Form, at the end of a posture, the hips are square to the direction you are facing. In transition the hips should remain level. In motion, the waist/hips guide the direction of the limbs.
The hips are synonymous with the waist. The waist/hips is the axle. The movement of the limbs toward/away or right and left should be guided by the waist/hips.
