By observing our facial expressions, we can gain a preliminary understanding of our physical condition. The color and luster of the face can directly reflect a person's health status. For example, if the face turns pale, it may be anemia or poor blood circulation; If the face turns yellow, it may be due to liver disease or malnutrition; If your face turns black, it may be due to kidney disease or prolonged staying up late. However, these are only preliminary judgments. If obvious symptoms appear, it is still recommended to seek medical attention in a timely manner.
通过观察脸色，我们可以初步了解自己的身体状况。面部的颜色和光泽可以直接反映一个人的健康状况。比如说，如果脸色发白，可能是贫血或者血液循环不良；如果脸色发黄，可能是肝病或者营养不良；如果脸色发黑，可能是肾脏疾病或者长期熬夜当。然，这些只是初步的判断，如果出现了明显的症状，还是建议及时就医。
