In what year did tanggou Town Dragon in Zongyang County, Anqing City appear?

About 40 years ago, my mother said she had seen it. At first, I didn't believe it. Later, she asked me about my period. She is a more rational person. She said she saw it, too At that time, there was only radio and the media was backward, just like my mother said, so I believe there must be dragons in this world.
