On October 15, Zaduo County, Yushu, Qinghai, was located at the source of the Lancang River, with an average elevation of 4,200 meters.

The Second Complete Primary School of Zaduo County is a reconstruction project after the earthquake in Yushu. Since 2016, the school has included environmental protection courses as school-based courses in its teaching plan. It arranges one class every week to provide environmental protection education for the third grade and above. Waste beverage bottles and cartons are used to make handicrafts, sing environmental songs, and write environmental slogans in Tibetan calligraphy to cultivate students' environmental concepts.

  There is a "garbage exchange point" at the entrance of the school, which is a lively scene every day.

The children hand over the plastic bottles picked up by the roadside, used workbooks, bones, and non-recyclable garbage to the "salesperson", so they can earn stationery with their own hands in the form of "waste for goods" without spending a penny , Food and supplies.
