This work is a USB flash drive design, inspired by the name and terrain of Huludao. Therefore, the USB flash drive adopts the shape of a gourd. "Gourd" also has the term "Fulu". The font on the USB flash drive is also a special-shaped Fu He Lu, the rotary type is adopted because the gourd is homophonic with "earning Fulu", and the name "Xiude Zhengguo" is also a good wish.
