The black bird perched on the branches of the cedar, the spruce spreading its arms, and the wind casting its moving footsteps on the ground of the house. The huge glass above its head resembled a calm water surface, with clouds flowing over it, and the bird lightly touching and flying away. Light gradually fills the space, and day grows rapidly. Thinking about small things while strolling, such as planting flowers and plants, preparing dinner ingredients, and cleaning the courtyard, life is within the space we have built.
