In the design work of the design company, the whole system process design went through three months. Although it was very hard during that time, I learned about the design from the system and had a new understanding of the design process. From receiving the project to analyzing and investigating the pain points, to sketching man-machine creativity, to the final verification of the modeling handle of the scheme, I was deeply impressed, I would like to thank my friends (Guo Zong, Lu Jie and Peng Ge) who helped me.
