Starting from the ancient Silk Road, the work is conceived to show three traffic scenes from ancient times to the present, from sand road to highway, from highway to railway, which expresses the spirit of "Silk Road" as an important part of Chinese culture. it supports the continuous improvement and modernization of transportation facilities in our country, which is not only cultural self-confidence, but also cultural heritage. With the seal as the carrier, the seal is a symbolic and valuable item or a cultural heritage with aesthetic value. We have integrated the three traffic views into the seal, reflecting the cultural spirit of the Silk Road.
