Why do old people also have Kirin tattoos in grave robbery notes? What's the meaning? Why is Wu Xie's blood so special?

It's just a Miao tattoo. Du Shou said: "In ancient times, Miao people had wet fever, and this tattoo can be used to detect the temperature of children." Custom doesn't mean anything. Naively ate the unicorn in the Lu Palace (that is, the fragments from that armor), so the blood was not as bad as the bottle. Original text: "Kirin failure is a blood clot formed by the coagulation of Kirin's blood. It is a valuable Chinese medicine, but it is not real Kirin blood, but the juice of a plant called Kirin blood vine, also known as blood snake vine, which is generally found in the south. The longer the unicorn is kept, the better the efficacy. At first, it only had some common functions, usually used as medicine, but there is also a rare usage in Chinese medicine, which is used to smoke corpses. In ancient times, the custom of some ethnic minorities and some mountain villages put a unicorn on the navel of the corpse and gathered it together, which can eliminate the yin of the corpse. The corpse will rot, but it will not attract maggots. Kirin failure will gradually develop from dark red to black with age. The longer the age, the darker the color. At a certain time, the nature will change, the mouth will melt, and people will eat it. Blood is not close to evil insects, and even mosquitoes dare not look for you in summer. Of course, this is just a legend. Master Liang just heard it from others. Seeing this for the first time today, I began to believe that it really happened. As for whether there will be side effects, there is no relevant record, but traditional Chinese medicine is generally very toxic. He told me not to worry: "I don't want to, I think the most troublesome thing is those bugs." "
