Doorways to the Earth (地門, Di Men)

A set of twelve points located around the groin and legs that regulate the lower orifices and are indicated for disharmony in the lower body with downward rebellion and sinking of Qi or Blood. They are not mentioned in the early classics but rather developed by Jeffrey Yuen as a counterpoint to the Windows of Heaven and are usually confluent points of the Divergent Meridians. They are:

Taiyang & Water
Weizhong Bl-40Descends Excess Yin from pelvis
Henggu Kid-11Shriveling of the genitals
Shaoyang & Wood
Huantiao GB-30Lowers Yin towards the pelvis to treat vaginal dryness
Jimai Liv-12Hernia
Yangming & Earth
Qichong St-30Raises Yin upwards to the pelvis to treat swelling and pain in the genitals
Chongmen Sp-12Inability to urinate
Pelvis & Du/Ren Mai
Chengjiang Du-1Raises Yang to treat haemorrhoids
Mingmen Du-4Tonifies Yang to treat intestinal prolapse
Huiyang Bl-35Warms the Interior to treat leukorrhea and leakage in the Lower Jiao from Deficiency Cold
Huiyin Ren-1Clears Empty Heat to treat anal swelling and genital itch
Qugu Ren-2Raises Yin to treat leukorrhea and leakage in the Lower Jiao
Guanyan Ren-4Tonifies Yin
They may also be combined with Window of Heaven points to balance above and below.

A different way of determining this grouping that is more in line with the Window of Heaven points as used in the Neijing would be to determine the points where pulses are felt in the lower body. This would imply: The femoral pulse: Jimai Liv-12 Chongmen Sp-12 Qichong St-30 The popliteal pulse: Weizhong Bl-40 The dorsalis pedis pulse: Chongyang St-42 Taichong Liv-3 The posterior tibial pulse: Taixi Kid-3 Radial pulse: Taiyuan Lu-9 Princeps pollicis pulse: Hegu LI-4 These last two may seem unusual as they are on the upper limb, but in the Renying-Cunkou pulse system of Ling Shu ch. 9, the radial pulse represents the relative strength of Yin, while the carotid represents the relative strength of Yang, and when the arms are by the sides, these pulses are actually level with the waist. Alternatively they could be considered the pulses that correspond to Man in a Heaven-Man-Earth paradigm, although a paradigm similar to this is already expounded in Su Wen ch. 20, on The Three Sections and Nine Indicators.
