Friends have smart holes on both sides of their ears. What's your opinion?

"Zhixue" is a folk name, and it is also called "Mi Cang, Cang" in some places, and "congenital preauricular fistula" in medicine. In fact, it is a common congenital malformation.

Superstition says it's called spike barn, and there are: load grain first and then bran; It means blessed.

My sisters and I have a pair of "ear boxes", but my parents don't. When I was a child, my aunt called them "smart eyes", but in fact we couldn't see them without paying attention. The three of us have always been proud of them. I didn't know it was a congenital malformation until I grew up, and I felt very afraid that my next generation would have it.
