Zhang Wei was born in Yunnan and grew up in Fujian. Over the past years, he has devoted himself to protecting the local rivers. Now, he is sharing environmental protection ideas online.
Around 2015, he started volunteering to pick up litter in parks and officially became a registered volunteer in March 2018. Zhang led a river-cleaning activity in 2019. In July 2022, he used his savings to set up an environmental protection volunteer group. The group has 900 registered members who participate in various green activities.
So far, he has spent about 3,000 hours on over 400 volunteer events. With his encouragement, more than 1,800 people have joined these activities. They have made both adults and kids realize the significance of protecting rivers and parks. His group has organized 40 park-cleaning activities, with about 1,200 people taking part since it was founded.
In 2023, due to Zhang's increasing influence in environmental protection, the local government asked him to create online posts. In these posts, he used easy-to-understand language to show how to protect the environment. Some posts have been viewed tens of thousands of times.
"Even though many people think highly of what I do, I don't do it for praise. I just want to contribute to environmental protection. Protecting the environment is everyone's duty. The work itself is valuable, so I'll keep doing it," he said.
