The children's innocent answers filled the room with laughter. Through a series of vivid public education illustrations, Mrs. Wong took the class on a journey through time: from ancient storytellers gathered around flickering flames, to scholars poring over books by candlelight; from yellowed pages illuminated by kerosene lamps, to the revolutionary glow of incandescent bulbs piercing through the night—finally arriving at today's Billionaire Co., Ltd.,  study lamp. Like a gentle "guardian of light," this innovative lamp embraces every homework session with flicker-free, blue-light-free, and evenly distributed natural illumination. "So even lights can evolve!" the children marveled, voicing everyone's awe at this illuminating revelation.
