Teacher leads students to protect 'mother river'

Dong knows it's important to get more people for river protection. So he launched the Green School with Love and Care project in 2011, which took the Ulan Mulun River as the target and has carried out more than 20 activities to protect it. To enrich the project, Dong has done nine field studies in Ordos covering thousands of kilometers.

Over the past 10 years since the project was established, the number of participants has exceeded 5,000. As many as 1.5 million plastic bottles, 300 tons of waste paper and 20,000 used batteries have been disposed of properly or recycled. In addition, those recycled items have also endowed a charity fund. In 2020 in the context of the pandemic, the project has donated medical supplies worth more than 60,000 yuan to Hubei province.
