Long ago, Hmong people have "love festival" where young men and young women go to find husbands and wives.
During the festival, Poj Ntxoog (the unseen/spirits) also come to find wives and husbands...
Poj Ntxoog would attend the festival. The handsome ones and the beautiful ones would often die after the festival because
Poj Ntxoog would take them to be their men and women.
Hmong people decided to wear silvers all over their body and clothes.
Another year later, Hmong people again celebrate the annual "love festival."
Poj Ntxoog would come out to find husbands and wives, but as they came, they did not find any
handsome or beautiful ones. Poj Ntxoog came, but only saw the old elderly folks.
People could see the handsome and the beautiful women and men playing and singing, but
Poj Ntxoog couldn't see them at all.
The silver "ci" or blinded the eyes of Poj Ntxoog. This is why, Hmong people wear silver, as a way to
make themselves invisible from the eyes of Poj Ntxoog.
