《Secrets of the heart》

Produced by CMG Documentary Center, “Secrets of the heart” is China’s first documentary systematically exploring cardiac science. Its poster has exceeded 100 million views since release. The film showcases real-life mechanical heart implants and surgeries, with its poster hailed as a breakthrough in medical documentaries for blending emotional depth and symbolism.
The hand-painted artwork (non-3D/AI) portrays the heart as a precision “machine” in our chests—an eternal subject of human exploration. Surgery mirrors repairing such machinery: time-sensitive and intricate. A mechanical heart dominates the poster, juxtaposed with anatomical diagrams to provoke reflection. An open window and lively birds on the heart symbolize repairability, faith in science, and life’s hope. Central red hues evoke vitality, reflecting medical miracles.
A restrained palette—sophisticated greys and radiant light—creates spatial depth, evoking rebirth. Interlocking gears, electric currents, and arteries highlight cardiac functions, while leaves, birds, and musical bubbles soften mechanical rigidity. The avant-garde, cyberpunk-inspired fusion of steel and flesh, reality and surrealism, leaves a lasting impact.
Cardiac surgery embodies rebirth, reverence for life, and the creation of miracles.
