Traditional Chinese Medicine believes that meridians are important components of the human body, carrying nutrients such as qi, blood, and body fluids, communicating with the inside and outside, and regulating internal and external organs. If the meridians are blocked or obstructed, it will affect the normal functioning of the body, leading to the occurrence of various diseases.

Meridian blockage can cause a series of symptoms. Firstly, there may be discomfort such as pain, soreness, and numbness in certain parts of the body due to blockages in the meridians, which prevent the circulation of qi and blood and affect the normal function of that area. Secondly, the function of the internal organs will also be affected, resulting in corresponding symptoms. For example, blockage of the heart meridian may lead to symptoms such as palpitations, chest tightness, insomnia, etc; Blockage of the liver meridian can cause rib pain, irritability, menstrual disorders, and other symptoms.
中医认为，经络是人体的重要组成部分，它承载着输送气血、津液等营养物质，沟通内外、调节脏腑的功能。如果经络不通，经络堵塞，就会影响到身体的正常运转，从而导致各种疾病的发生。

经络堵塞会引发一系列症状。首先，身体局部可能会出现疼痛、酸胀、麻木等不适感，这是因为经络堵塞导致气血不能流通，影响到该部位的正常功能。其次，脏腑功能也会受到影响，出现相应的症状。例如，心经堵塞可能导致心悸、胸闷、失眠等症状；肝经堵塞则会引起胁肋胀痛、烦躁易怒、月经不调等。

The twelve meridians are closely related to various organs and viscera in the human body. Each meridian is associated with a specific organ, and the health status of the organ can be determined by the smoothness of the meridians. For example, problems with the lung meridian may lead to symptoms such as coughing and wheezing. Therefore, by stimulating acupoints on the meridians or performing corresponding treatments, the balance of yin and yang can be adjusted, the physiological functions of the human body can be regulated, and diseases can be cured.

The twelve meridians are extremely important basic concepts in traditional Chinese medicine theory, serving as channels or pathways for the flow of vital energy in the human body. Through the Five Elements Health Preservation Method and theories related to organs and meridians, it is possible to comprehensively regulate human life activities, prevent and treat diseases, and maintain physical health and balance.
十二经脉还与人体各个脏腑器官有着密切的联系。每一条经脉都与特定的脏腑器官相关联，通过经脉的通畅与否，可以判断脏腑器官的健康状况。例如，肺经出现问题可能导致咳嗽、气喘等症状。因此，通过刺激经脉上的穴位或进行相应的治疗，可以调和阴阳平衡，调整人体的生理功能，治愈疾病。

十二经脉是中医理论中极其重要的基本概念，是人体生命能量流动的通道或途径。通过五行养生法和脏腑经络相关理论，可以全面地调控人体的生命活动，预防和治疗疾病，保持身体的健康和平衡。
