At around 1:40 PM on the afternoon of the 12th, while visiting the Baima Park, Nanjing photographer Qingchun Cao was surprised to discover eight white straight-line cloud bands in the deep blue sky above the main peak of Zijin Mountain, radiating beams of light, and exceptionally beautiful. "I have never seen such a spectacle in my sixty-plus years." Mr. Cao rushed out of the park in one breath, and selected three shooting points from which he took more than a dozen excellent pictures. According to his revelation, this amazing spectacle lasted exactly nine minutes. Afterwards, the radiating beams of white clouds slowly dissipated and disappeared.
