A young woman is giving a presentation in a classroom. She wears glasses and a brown jacket, and stands in front of a projector screen displaying an image from China Daily. The screen reads "the 24 solar terms are hailed as 'the fifth great invention of China.'" The classroom is bright and well-lit with rows of empty blue and white desks. A digital clock on the wall displays 14:07. The woman is holding a small object in her hand and looking at it. She appears to be preparing to speak.
