Concrete has always been a dull, rough, gray, and stiff impression. In my impression, concrete has the unique wild temperament of the "brown masters", when the hard-bridge hard horse, the unbreakable concrete, gives off a warm glow. When the LED bulb is lit, the gentle light is enough to dissolve the wild gas of the "brown masters", and the wild is also gentle.
