The formation process of wealth bag is like this:

The normal physiological curvature of cervical vertebra is lordosis and thoracic vertebra is kyphosis.

At the junction of neck and chest, it is just the junction of lordosis and kyphosis.

When the lower cervical vertebra is excessively lordosis and the upper thoracic vertebra is excessively kyphosis, a bony cervicothoracic combined bony package is formed.

This forms a wealth bag.

This kind of bone wrapping directly affects the attached muscles, so the related muscle groups are tense, twitching and swollen, the first and second ribs on both sides are also turned over, and the muscle groups between the vertebrae and ribs are also swollen and twitching, and even the turned-over ribs spread to the scalenus muscle, narrowing the space between the scalenus muscle.

In this way, the swelling of muscles makes the bone bag bigger and more prominent, forming a "rich treasure", which can be used externally, easily applied or acupuncture.

Some wallets will increase year by year with the growth of age, and some will become harder and harder. In severe cases, it is like a stone embedded in the back of the neck, which directly oppresses the cervical nerves, leading to poor meridians and blood flow, and the head can't move or lift.
