Those Folklore Stories Left in the Corners of History

As a student of history, I occasionally come across strange and mysterious folk customs and surprising and twisting stories when browsing historical materials and checking archives. However, due to various reasons, it is difficult to have a clear ins and outs of these things, and it is inconvenient to explore, so I wrote them down and adapted them into some stories. If it can arouse everyone's interest, that would be great. PS: Each story will be accompanied by some research papers on it, and the author's ideas are generally inspired by these. Please make your own judgment and study.
