My mother and I came to the mountains, my mother picked up a leaf on the ground, said: “Winter is over, the warm spring has finally arrived.” I looked at the hands of the mother leaves, looked up and looked at the sky Floating white clouds, I thought: the leaves will fall, white clouds why not fall? I could not help but ask her why is this
