2026 Chinese city series promotional posters with the theme 【北京】. Modern, colorful, bright and transparent national trend, vertical version 9:16. A large area of ​​white texture leaves the background blank, and a strip of red silk spiraling from the lower right to the upper left forms the S-shaped main composition. In the lower right corner, an Oriental woman is waving red silk. Her clothing must be customized based on Beijing's regional culture. The red silk extends into a long urban scroll, integrating the Temple of Heaven, the Great Wall, the Bird's Nest, Labagoumen (喇叭沟门) Primitive Forest Park, Shichahai, and Beijing-style cross talk. Typesetting on the left is SPRING 2026, vertical Beijing and small seal “北京”. It requires a unified sense of series, but no similarity, rich details, and strong urban recognition. The text is clear and beautifully laid out, with high-end graphic design.
