Ye Tianshi's famous saying "Where you are sick for a long time, the disease will be in the network, and the network will be full" embodies profound medical wisdom. The fullness he mentioned is not a simple bloating abdomen, but covers many complex diseases such as swelling, accumulation, single distention, and water and malaria. It seems easy to understand how to get sick for a long time, but how the network can lead to fullness needs to go deeper**. In Yip's theory, the meridians are the bridges connecting the meridians and the viscera and muscular organs, just like the intricate transportation network in the human body. The meridians run vertically, like the main road, leading the qi and blood of the whole body; The meridians are like capillaries, which are responsible for transporting qi and blood to every corner. When the viscera qi and blood are weak, although the meridians will also be affected, at this time, the disease is still in the qi and has not yet penetrated into the blood. However, once the disease and evil penetrate deep into the veins, the blood will be empty, and the pathway for the transmission of qi and blood will be blocked, resulting in the lack of qi and blood between the viscera, resulting in fullness. This exposition of Ye Tianshi not only reveals the mechanism of long-term illness into the meridians, but also emphasizes the important role of the meridians in maintaining the balance of qi and blood in the human body. When the qi and blood are not continued, the veins and veins are empty, and the stagnation will form diseases such as stagnation and water. This kind of pathological state of poor qi and blood, and the relationship between the virtual and the real, is a typical manifestation of the "long-term illness into the network" emphasized by Ye. Therefore, for the long-term illness, we should not only pay attention to the conditioning of the meridians, but also pay attention to the dredging of the meridians. Only when the qi and blood are smooth and the viscera is coordinated, can the occurrence of diseases such as fullness be avoided. Ye Tianshi's theory provides us with valuable medical enlightenment and points out a new direction for us to be ill for a long time. 
Xu Lingti was critical of Ye's disease in the "Guide Medical Case", believing that it was "apocryphal". However, after careful analysis, it is not difficult to find that Ye's thinking is in-depth while Xu's insights are slightly superficial. Wang Shishan once said: "The flesh and blood of the human body are like wind and water, and if the wind is fast and the water is urgent, the embankment will collapse and be unstoppable; When the wind is calm, the sand and gravel become obstacles, and the flow of water is blocked. This metaphor provides a new perspective for us to understand the mechanism of local qi and blood stagnation caused by the weakness of qi and blood. The disease of the meridians discussed by Ye is precisely on the basis of the weakness of qi and blood, which leads to the poor flow of qi and blood due to various factors, and then forms a pathological state of paralysis of the meridians.
Wang Shishan's exposition just provides a powerful footnote to Ye's statement. Just as strong winds and waves can destroy dams in an instant, the qi and blood in the human body are also susceptible to the invasion of internal and external evil qi in a weak state, resulting in disordered flow of qi and blood and the formation of network disease. When the qi and blood are calm, although there are obstacles caused by sand and stones, the water flow can still move slowly, and the qi and blood in the human body can also maintain normal operation. Therefore, the theory of network disease advocated by Ye is actually a profound revelation of the pathological changes of the body in the state of qi and blood weakness.
To sum up, Xu Lingti's criticism of Ye's disease may be too arbitrary. From the perspective of local qi and blood stagnation caused by weakness of qi and blood, Ye provides a unique perspective for us to understand network disease. And Wang Shishan's argument provides strong support for Ye's statement. Therefore, we should deeply understand the connotation of Ye's disease in order to better apply this theory in clinical practice.
