Wang Xuan, a scholar from Wuxi, presided over the development of "Chinese Character Laser Phototypesetting System", known as "Contemporary Bisheng". The exhibition hall is vivid and intuitive from the scene of mother's instruction in childhood to the memory of "nine deaths and one's life" in the Cultural Revolution. Finally, there is a "experience area of typesetting", which allows visitors to choose the font and output the following Chinese characters - "raising their heads to look at the bright moon, bowing their heads to homesickness".
