UFO sightings record of the Song Dynasty

During the Jiayou period (1056-1063), there was a large pearl mussel in Yangzhou, which could often be seen in dark weather. The earliest in the lake in Tianchang County, then into the Yongshe Lake, and later in the newly opened lake, for more than ten years, the residents in the middle of the river are often seen. My friend had a study on the lake, and one day on the edge of the day suddenly saw this pearl mussel particularly close, at first slightly opened the mussel shell, the light came out of the mussel shell, like a horizontal gold thread. The next moment suddenly opened the shell, there was half a mat the size, the white light in the shell was as bright as silver, the beads were as big as a fist, the light could not be looked at directly, and the trees more than ten miles away had shadows, just like the light at sunrise, and the red elephant flames could be seen in the distance. Suddenly gone, like a fly, floating on the waves of water, looking like the sun from a distance. In ancient times, there was the pearl of the bright moon, and the color of this bead was not like the moon, but had a flame-like glow, a bit like the sun's rays. Cui Boyi once wrote "Pearl Fu", he is a High Postman, and may often see it. I haven't seen it again in the past few years, and I don't know where I flew. Fanliang Town is the place where the pearl mussels are infested, and pedestrians come here, often stopping the boat for a few nights to wait to see it, and the pavilion by the lake is named playing with the pearl pavilion.
