If the world is a blue sky, then everyone is a cloud in the sky; If the world is a trickle, everyone is a drop of water in the stream; If the world is a crystal clear pond, then everyone is a free fish in the pond; If the world is a colorful flower, then everyone is a little pollen in the flower; If the world is a clear water drop, then everyone is a never-ending water molecule in the water drop; If the world is a harmonious and beautiful home, then everyone is a close relative at home.
