LU 1: ZHONGFU (Central Residence)
ZHONG means middle and FU means place, this is referring to the middle jiao where the LUNG channel starts. The QI of the SP / ST are gathered into the LU MO at this point. The point is below the acromial extremity of the clavicle, 1 cun (pronounced "tsun"), directly below LU 2, 6cun lateral to the CV MO, in the first intercostal space. In the pectoralis major and minor muscles, in it's deep position, in the internal and external intercostal muscles.
The lung points all do great damage. LU 1 must be struck with a smaller weapon such as a one-knuckle punch. Great Qi drainage and thus great local pain which will slowly spread over the whole chest area due to this point’s connection to SP 21. A strike here will hinder the progress of ‘GU Qi’, that which is made from food and liquid. So apart from the immediate effect of extreme pain in the whole chest area, the long term effect will be that the gu Qi will not be produced and although the recipient is taking food, the Qi from that food is going nowhere and so health and lifestyle are slowly diminished.
