A vintage socialist propaganda poster in a mid-20th-century Chinese style, printed on aged paper with a warm sepia tint, distressed texture, faded ink, and slightly worn edges. The composition is vertical and heroic. On the right half of the poster, show a large waist-up portrait of a male worker or revolutionary figure wearing a dark cap and a dark utilitarian jacket, facing slightly to the left with a stoic, determined expression. On the left-center, a white reusable rocket rises upward with bright engine flame, depicted like an aspirational symbol of technological progress; the rocket has the word "SPACEX" written vertically on its body and visible landing legs near the base. Behind the rocket, fill the sky with dramatic cream-colored sunburst rays spreading outward across a muted blue background. In the lower left, include a cheering crowd of exactly 6 factory workers or citizens in blue-gray uniforms, raising their hands in celebration, with one large red flag waving beside them. Add faint industrial city elements and launch-tower silhouettes behind the crowd. At the bottom, reserve a wide text panel with large bold red Chinese slogan lettering in two lines reading: "今天回收火箭，明天建设星际家园！". Use a screen-printed poster look, painterly realism, limited palette of dusty blue, cream, brick red, and dark olive, with strong ideological poster composition, triumphant mood, and retro-futurist space-race symbolism.
