Inspired by one of the oldest tree species in the world - Iron Tree. The top big feather leaves of the iron tree are as clean, smooth, bright and lovely as super large feathers. The designer uses the lines with thorough and continuous handwriting as the expression technique. The lines are long, thin and strong. The straight and upward leaves are depicted vividly, as if they are growing upward. The strokes are delicate, soft and beautiful. The layers are clear. The composition is equal. The unique large-scale patterns make the indoor space full of vitality.
