PERSONAL PROJECT | 2022
In this project, I think the design could draw more attention to some social phenomena and solve social problems. When walking on the streets, I noticed that many street vendors were still surviving in an unstable environment without the right safeguard. Therefore, I design a new street vending mode that combines a minineighborhoods. I hope technology could allow marginalized groups to express themselves and bring convenience to them as well.

I think the design may be a medium that could convey value, information, and truth. I got my inspiration from a documentary of physical appearance. appearance frequently but the mirror would put more mental pressure on them. From this point, I design a mirror that helps users control their behavior and record their mood. In this way,

I believe design can serve people solve problems and make their life more convenient. The purpose of this design is to help people who pursue a healthy diet and want to eat better but don’t have sufficient knowledge about food nutrition and have difficulty finding the right food for themselves.
