相通 (pronouced as sahng tong in korean) means mutual communication. in acupuncture, it means the communication between certain Zhang Fu pairs as follows:
KD-SJ
LV-LI
SP-SI
HT-GB
LU-UB
PC-ST
recently there were a couple of patients with anxiety symptoms along with various GYN disorders. their s/s look very complicated because it looked like a confusing mixture of LV SP HT SI s/s. tonify SP took care of it all because of this SP SI sahng tong communication.
