What is the purple auspicious cloud in Liu Bang's photo?

There is no scientific basis for saying that there is purple auspicious clouds in Liu Bang's photos, but it is just a false rumor on the Internet. The incident of purple auspicious clouds in Liu Bang's photos is actually a rumor circulating on the Internet. This rumor first appeared on 20 15, when a picture was circulated on the Internet, which was taken in huayin city, Shaanxi Province. A purple auspicious cloud appeared in the sky in the photo. It is said that this auspicious cloud appeared unintentionally when shooting. Later, someone linked this photo with the historical figure Liu Bang and fabricated a story, claiming that it was evidence of Liu Bang's "apparition". But this story has no historical basis, and the photo itself has some problems. Some professionals have analyzed this photo and think that this purple auspicious cloud may be caused by the optical fault of the camera or the effect of post-processing, and it is not a real natural phenomenon.
