A realistic photo of a Chinese high school math exam paper, printed in black and white on slightly gray paper, titled “Math Exam Paper”, with multiple choice questions and math formulas, including a small 3D geometry cube diagram. The paper is photographed casually with a smartphone, slightly tilted, with uneven lighting, soft shadows, and minor blur. The text is in Chinese with a mix of bold title font and standard serif body font. Realistic paper texture, exam layout, authentic classroom test sheet style.
