4 oz is the result of internal strength. A cat touches lightly because it is already buoyant. An average person, trying to give 4 oz, collapses their frame. Without internal strength, 4oz is conceptual.

Ming jing

Intermediate students must work towards acquiring 'ming jing' - obvious power.
 Requirements:

 • Some degree of exaggerated, large movement
 • Connection through the back
 • Rotation of the axis
 • Large waist turns
 • Distinct weight shifts
 • Remain balanced at all times
 • Take the balance
 • Do not strike a rooted body
 • Keep the muscles soft (relaxed)

 Be very careful not to use muscle tension (contraction), locked joints, disconnected arms or force against force.
