Are you concerned about bloodletting and geomantic omen in Tang Yin?

No. Tang Yin point, from the Jade Dragon Sutra of acupuncture and moxibustion in Shen Ying, Bian Que, is located in the depression between the head and the inner end of the eyebrows. Tang Yin's location is special, and bleeding on the face is easy to bruise, which affects the appearance and is also easy to be risky. Therefore, self-bloodletting treatment is generally not recommended. If you don't feel well, you should go to the hospital to see a doctor first.
