In Shanghai，when people throw away wet waste，they must take the wet waste（mainly food waste） out of the rubbish bag first.Then，they throw the rubbish bag into another trashcan（垃圾桶）.This is not easy to do.
   Shi Yuan is a 14-year-old student from Shanghai Wenlai Middle School.One rainy day in May，2019，when he was throwing away wet waste，he got food waste all over his trousers.Then，he decided to do something about this.He made a special rubbish bag for wet waste.The bag has a band of adhesive tape（黏膠帶）.When one end of the tape is open，the bag turns upside down by itself.Then，people can easily throw wet waste into the trashcan.Shi's idea won him a prize in the Shanghai Adolescents Science &Technology Innovation Contest.So far，he has sold over 2 million bags online.And on May 4，2020，he began to sell his bags in 11 supermarkets in Shanghai.
   "Like many other kids，I'm also busy with homework and I like to play.The only difference is that I like to find ways to make life easier，"Shi said.
