Creative brief introduction: the design name of the torch is "rain brocade", inspired by Chengdu Shu embroidery silk rain brocade, combined with the simple and slender shape of Chengdu bamboo piano. There is an oblique bottle opening above, which is not only a call for friends from all directions, but also means the Sichuan Basin, where Chengdu is located. The outside is painted with gradual fading lines in the direction of the meridian, implying that the meridian of silk rain brocade is also like fine rain silk, which moistens all things in Chengdu and nourishes guests from all directions.
