    As Shanghai prepared to introduce mandatory(强制的) garbage sorting on July 1, games and toys that examined fun ways to spread information about the garbage sorting were to encourage younger people to take action.

A 15-second video of a game went on Chinese social media. In the video, players wearing VR(虚拟) headsets saw four different types of trash can in front of them, and had to throw different types of garbage into the right buckets(桶) to get points. Although it was not the only VR game in the place, visitors lined up around the booth to explore it because of the garbage-sorting theme.

“As a Shanghai, I am in great need of this game. Maybe I won’t need to check how to categorize(分类) each piece of garbage on my phone while going through all my garbage every day if I play this game more often, ” said ZhouZhou, a young Shanghai. But some social media users in Shanghai have complained about the difficulty of sorting different types of garbage.

Wu Xia, founder and CEO of VitrellaCore, the company that created the game, said the idea was to provide an interesting way of learning about garbage sorting. “It’s simple and easy to understand. People can practice sorting garbage without actually going through their trash, and it is a more effective method than using paper materials when training volunteers,” Wu said.
