The blood and qi of the ten meridians all originate from the Jing-Well points and terminate at the He-Sea points. They sequentially flow into the Jing-Well, Ying-Spring, Shu-Stream, Jing-River, and He-Sea points without cease. Someone asked: There are twelve meridians in the pulse, why only speak of ten meridians? Why not mention the remaining two meridians? The answer is: These two meridians are the Sanjiao (Triple Burner) Meridian of Hand-Shaoyang and the Pericardium Meridian of Hand-Jueyin. The Sanjiao is the father of Yang Qi, and the Pericardium is the mother of Yin Blood. These two meridians are respected and are not governed by the Five Elements. Their main function is to receive and nourish the blood and qi of the other ten meridians. Therefore, only the yin and yang pulses of the ten meridians are discussed. Each day, they flow through the Jing-Well, Ying-Spring, Shu-Stream, Jing-River, and He-Sea points for five shichen periods respectively, then return to their home meridians. These two meridians also each flow through six acupoints (Jing-Well, Ying-Spring, Shu-Stream, Yuan-Source, Jing-River, He-Sea), allowing one to understand the circulation of the twelve meridians throughout the body.
Sanjiao Meridian: Guanzhong (LI1, Yang Jing-Well), Yemen (TE2, Ying-Spring), Zhongzhu (TE3, Shu-Stream), Yangchi (TE4, Yuan-Source), Zhigou (TE6, Jing-River), Tianjing (TE10, He-Sea). On days when the Heavenly Stems are Yang and combine, these six acupoints are infused. For example, on Jia days during Jia-Xu hour up to Jia-Shen hour, this is the time of Yang Stem combination.
Pericardium Meridian: Zhongchong (PC9, Yin Jing-Well), Laogong (PC8, Ying-Spring), Tailing (PC7, Shu-Stream), Jianshi (PC5, Jing-River), Quze (PC3, He-Sea). On days when the Heavenly Stems are Yin and combine, these five acupoints are infused.
For instance, on Jia days during Jia-Xu hour, the Gallbladder Qi first emerges at its Jing-Well point; during Ji-Si hour, the Spleen Blood emerges at its Jing-Well point. Yin and Yang proceed together. On Yang days, Qi moves first and Blood follows; on Yin days, Blood moves first and Qi follows. From Ji-Si hour to Ji-Mao hour is the time of Yin Stem combination. For other stems and hours, all follow this rule.
Including the previous ones, there are sixty acupoints in total, forming sixty "Shou" (cycles/phases). Each acupoint accounts for 1/60th of a ke (quarter-hour), specifically 1 liang 6 fen 6 li 6 hao 6 si 6 hu 6 miao. This is the temporal allocation for one acupoint.
Sixty acupoints constitute one hundred ke in a day. During each shichen period, the generating cycle nurtures the offspring five times, flowing through the Jing-Well, Ying-Spring, Shu-Stream, Jing-River, and He-Sea points. Over twelve shichen periods in day and night, Qi and Blood pass through sixty Shu points. To know where the human Qi resides, one can use the Wuzi Jianyuan method to calculate days and hours. Thus, the sixty Shou method is a flexible approach, and treating diseases based on Jing-Well and Ying-Spring point needling is extremely effective.
On Jia and Ji days, Bing hour is the start; on Yi and Geng days, Wu hour is the head; on Bing and Xin days, calculation begins from Geng hour; on Ding and Ren days, flow proceeds smoothly from Ren-Yin hour; on Wu and Gui days, Jia-Yin hour sets the timing. The sixty Shou method assists medical practitioners.
