a cultural theme poster reflecting the spirit of chinese song-ming confucianism. at the center stands the back of an ancient scholar between heaven and earth, robes gently blown by the wind, posture calm and resolute. above are celadon-blue mountains and dawn light; in the middle are layered images of open ancient books, bamboo slips, academy windows, and ink-wash textures; below are rivers, fields, city walls, and thousands of homes with lights. a warm golden pillar of light runs from the sky through the figure to the earth, symbolizing the spiritual inheritance of "establishing the heart for heaven and earth, establishing the destiny for the people, continuing the lost learning of the sages, and opening peace for ten thousand generations." the visual language combines song-dynasty painting aesthetics with modern conceptual poster design, using celadon blue, rice white, ink black, and dark gold, with generous negative space, subtle paper texture, ink-wash layers, solemn, vast, clear, and culturally responsible atmosphere. at the top, the restrained modern serif title reads "hengqu four maxims." at the bottom, vertical small text reads "为天地立心，为生民立命，为往圣继绝学，为万世开太平." the text is clear, dignified, pale gold, and does not overpower the image. cinematic eastern humanistic illustration, high-level graphic design, rich detail, 8k,
