On October 3, 2022, I was on a 2,000-meter-high mountain. The originally sunny weather suddenly came with a cloud of mist. The sunlight formed multiple beautiful oblique rays through the cracks in the trees, and also formed a beautiful Corona due to diffraction. Corona is very colorful. As the clouds move, the oblique light and Corona also change. Video link: https://www.youtube.com/shorts/yijvK7XOHhY.
