Pork pie soup is still not recommended to add beef. Because from the perspective of Chinese medicine, pork is sour and cold, slightly cold, and has the nature of nourishing yin and dispelling cold. However, beef tastes warm, which can replenish the spleen and stomach, strengthen the waist and feet, and has the effect of calming the stomach and benefiting qi. One is warm, the other is cold, and the other is cold and greasy, which conflicts with the taste and is easy to damage the vitality and is not suitable for eating together.
