Why did the ancients think that Tang Yin was black and there was a bad omen?
Although China used to regard white as beauty in ancient times, even now there is a saying that white covers all the ugliness! But in traditional physiognomy, the viewpoint is more objective. I think white is also good or bad! It is taboo to make people's nails white! Also taboo people white as colorless as lard! I think it's white and unhealthy!
The blackening of Tang Yin is not only a bad omen on the face, but also a bad omen in Chinese medicine! According to the theory of traditional Chinese medicine, a person's lungs and kidneys are sick! Then his Tang Yin will be black! Because the client already has a disease, the physiognomy thinks that this person must have a bad omen!
Of course, liars also use this to deceive people! If you are not black, you must say that you are black!
If the person's skin is already black, that's not bad! As black as a bird's feather, shiny and vivid, it is not only healthy, but also a symbol of health! This situation is not that Tang Yin is black!
