My Story: Few years back, my father worked as a secuirity guard in loyang valley. Now he is no longer working there because of one frightful night. This is what he told me.
The night was cool, and he was on his usual patrol duties around the estate at around midnight. When he was patrolling near the question mark(it is a place where the path is a "?" shape), he heard some little children laughing. Out of curiousity, he went towards the noise and to his fright, he did not see anything. When he turned around and continued his duty, he heard the laugh again. It was louder and it seemed that it was very near him. A chill ran down his spine, he turned and saw two little baby-like "people". When he shined his torch light at them to get a clearer view, he realised that it was not people but ghosts. He ran for his life. He ran as fast as he could to the guard house and informed all his colleagues. He was told that it was common to see things like that at question mark.
After that incident, he quit his job the next day.
