Shot in the mountains of Shaanxi, China, a cherry blossom tree by the cliff is full of branches, but the top is not in bloom, and the other branch is only in bloom at the top, but not at the bottom. Later, I searched for information that the new branches of the plant bloomed in a different order from the old ones. The old branches bloomed from the bottom, and the new branches bloomed from the top. I thought it was rich in natural philosophy, and I realized the Tao from it.
