What information about flying saucers was recorded in ancient China?

Wu, a painter in Qing Dynasty, looked like a work in his later years. There is a picture of "red flames flying". The picture shows pedestrians on the Suzaku Bridge in Nanjing, looking up at the sky and scrambling to watch the flickering flames. On the top of the painting, the painter wrote: At 8 o'clock in the evening on September 28th, in the south of Jinling (now Nanjing), I suddenly saw a fireball, from west to east, like a huge egg, red and dull, floating in the air, and its movement was very slow. When clouds cover the sky, it is dark. Looking up, you can clearly see that there are more than a hundred people standing on the Suzaku Bridge. About a meal, the commitment gradually decreases. There are also those called meteors crossing the border, but the stars are flying and fleeting. This ball is near and far, and has its own. Many people, poor speculation. There is a cloud, which is faintly audible at first, and does not listen to it from the south gate. Hey, it's different! A Qing Wu's inscription is a detailed and vivid witness report. The time, place, number of witnesses, size, color, luminous focus, flight speed and various speculations of the fireball passing through Nanjing are clearly described. This painting was painted by 1892 (18th year of Guangxu). 100 years ago, there were no such things as flying saucers and flying saucers in the world. Obviously, the painter failed to realize that this picture of "red flames flying" has become a precious historical material for people to study flying saucers.

Nowadays, some UFO experts believe that UFOs come from the bottom of the sea and their base is in the mysterious Bermuda Triangle. In many ancient books in China, there are descriptions of flying saucers related to rivers, lakes and seas. The most striking thing is a passage by Shen Kuo, a great scientist in the Song Dynasty, which is quite intriguing. What it tells is like a vivid record of another planet's plane's visit to China's Jiangnan water town.

"In Jiayou, there is a pearl in Yangzhou, which is very big and relatively common. Originally from Beize, Tianchang County, it was later transferred to Fushe Lake, and later in Xinkai Lake, which was often seen by residents and pedestrians for decades. Yu Youren's study is by the lake. One night, he suddenly saw his beads close together. At first, he opened his room slightly, and the light came out from his kiss like a golden thread. Russia suddenly opened its shell, which is half the size of a seat. The white light in the shell is like silver, and the beads are as big as fists, so you can't see clearly. There are shadows in the Woods more than ten miles away. As shown on the first day, the distant sky is as red as wildfire. In the distance, it flies, floats in Apollo, and looks like the sun. In ancient times, there was a pearl of the bright moon, not like the moon, but almost like sunshine. Cui Bo tasted' Pearl Fu'. Boyi, a Gaoyou native, looks so-so. I don't come back when I'm nearly thirty, and I don't know where to go. Liangfan Town is just around the corner. Pedestrians often wait and see by boat for several nights. The famous county pavilion is called "playing with pearls". Shen Kuo is a scientist who has made achievements in astronomy, geology, physics, medicine and many other fields in the history of our country. From 1072, he was appointed as the "celestial supervisor" in the Song Dynasty. He studies rigorously and works very hard. I don't have any dreams or superstitions about Yangzhou, a pearl. It is not difficult to see that Shen Kuo described a real UFO case, which is very similar to the eyewitness report of modern people.
