What they say

"Dark nights are part of our natural heritage. They are beautiful and inspiring. It's a pity that many people have lost their view of the night sky in recent years as a result of light and air pollution. We should promote protection efforts, such as setting up reserves to preserve the night skies for future generations."

Ma Yong, secretary-general of the legal sector committee at the China Biodiversity Conservation and Green Development Foundation

"I have been greatly inspired by the Milky Way and the universe. They have helped me a lot by clearing my mind and elevating my soul. In my paintings, I try to express the inner peace and emotions I feel (when watching the night sky). I adore nature and people learning from nature."
