1 Jing luo(Channel and Network Vessel System)Foot Yang–Yin connections (➞Fig. 1.15)
The foot Yang channelsare connected to the foot Yin channels
at the toes by branches that separate from the primary Yang
channels and run to the foot Yin channels (➞Fig. 1.15):
FIRST CIRCUIT
ST channel (zu yangming) ➡SP channel (zu taiyin)
ST-42 (chongyang) ➡SP-1(yinbai)
At ➞ST-42a branch separates from the primary ST channel and
travels to ➞SP-1.
SECOND CIRCUIT
BL channel (zu taiyang) ➡KID channel (zu shaoyin)
BL-67(zhiyin) ➡KID-1(yongquan)
THIRD CIRCUIT
G.B. channel (zu shaoyang) ➡LIV channel (zu jueyin)
G.B.-41(zulinqi) ➡LIV-1(dadun)
On the instep of the foot, at ➞G.B.-41, a branch separates from
the G.B. channel and travels to ➞LIV-Yang–Yang connections (➞Fig. 1.16)
The Yang–Yang connections between the primary channels are
located on the head. They are rather superficial and follow the
order of the channels within the circadian cycle(according to
the Organ clock ➞Fig. 1.7). These connections support the
communication between the hand Yang and foot Yang primary
channels in the cranial region, which convey Qi of the same
nature and quality (yangming, taiyang, shaoyang). They also
mark the connections between the Yang axes, also referred to as
hand–foot pairing (➞1.2.3), and serve as a link between above
and below.
FIRST CIRCUIT

L.I.-20(yingxiang) ➡ST-1(chengqi)
SECOND CIRCUIT
