When I arrived at the flyover ditch at 21:00 on the evening of May 29, it was still drizzle. I had no hope of shooting the next day. I opened the curtains in the morning and showed that what I saw in front of me seemed to be the flyover ditch of the south of the Yangtze River. Clouds and mists, plateau meadows, snowy mountains looming, lake water like mirror, picturesque scenery.
