The Forgotten Ancestral Graves in Our Alley

In our family's alley, at the very beginning, there are several ancestral graves, and my family lives at the other end of the alley. The ancestral graves are right in front of someone's house, and over time, people have almost forgotten that it's a burial site. It's said to have been there for nearly five hundred years. Most people in the neighborhood initially didn't even know that it was a grave site. The revelation happened when a child from the house in front of the graves, a seven or eight-year-old at the time, had to go to the bathroom at night. He asked his mother for some toilet paper, and as his mother was about to hand it to him from the window, she saw three people dressed in ancient clothing, facing west. She was terrified and started screaming and calling for help. By the time others arrived, there was nothing to be seen. They stayed there until morning, and when daylight came, the discussion began. It was the older generation that remembered there used to be a few graves, and they even added more graves when they were children. They decided to relocate the graves, a process referred to as "拔坟" in our area. I was in the fifth grade at that time, and when I returned from school, I saw three sets of human skeletal remains that had been dug up. There was a large red cloth covering the pit to shield it from the sun. Four coffins were placed nearby, and we could see things that looked like tiles with inscriptions and even some old coins (ancient copper coins). To this day, every time I return home, I run straight to my house when I reach the back of my house, avoiding looking in the direction of those graves.
