Shundong creates an annual brand image film for Yunda, connecting the streets of the city, the countryside, the frozen soil of the plateau and the top of the snow mountain with the real footprint of the courier. The language of the lens focuses on the back of the trek in the wind and snow, the sweaty tooling under the scorching sun, and uses the visual tension of "crossing dangerous peaks and towns" to interpret the brand core of "mission must reach"-every journey is to stick to the promise, and every knock on the door is a warm arrival across thousands of mountains and rivers.
