Why do you choose to climb mountains on sunny days?

The advantages of climbing mountains on sunny days are good vision, good permeability and easy to take pictures, but some mountains, especially the top of the mountain, have always been rainy and rainy, and the weather is like the top of Huangshan Mountain, which is rarely sunny.

Rainy days and cloudy days are slippery roads, which are unsafe.

If you find it useful, please adopt it. Thank you.
