What's the best photo you've ever taken?

I like the blue sky very much, and I have an inexplicable love for it. I usually take a lot of photos, especially in my hometown. There is a mountain near my hometown, and then it is not particularly high. I can climb to the top of the mountain in less than an hour. I like climbing mountains when I am free, especially when the weather is particularly good. I clearly remember that I took a photo of Zhang Quanjing at the top of the mountain, but not all the photos in my mobile phone have a panoramic view. I will always remember that photo, and now I really have that photo in my mobile phone. Nowadays, blue sky is not common.
