Fengjin usually refers to the acupuncture points on the fingers, not limited to one spot. It is recommended not to press the acupuncture points blindly to avoid adverse effects on health. There are many acupuncture points on the fingers, such as Shaoshang (LU11), Shangyang (LI1), Guanchong (SJ4), Shaochong (HT9), and Zhongchong (PC9), each with different effects. If one is invaded by wind-heat pathogens and experiences sore throat, fatigue, and other symptoms, treating Shaoshang (LU11) can aid recovery. Additionally, in cases of stroke coma, heatstroke, infantile convulsion, sublingual swelling and pain, or infantile nocturnal crying, treating Zhongchong (PC9) on the fingers may not cause significant harm to the patient's health. When treating acupuncture points, it is important to maintain a relaxed mindset, avoiding excessive tension and anxiety. Meanwhile, maintaining a good diet, avoiding overeating and binge eating, and refraining from spicy and irritating foods like chili peppers and garlic, is crucial to prevent interference with treatment outcomes. In daily life, it is essential to establish a good routine, avoiding frequent stay-ups to prevent weakening the immune system. Furthermore, exercising according to one's condition, such as practicing Tai Chi or Yoga, can strengthen the body.
