Wang Fengqin, a 61-year-old woman in Beijing, volunteers to sort(分类)rubbish in her living area in Beijing’s Chaoyang District.
At 6:30 every morning, while half of Beijing is still asleep in bed or enjoying a delicious breakfast, Wang rushes through her busiest hours in the day. She gets up, gives her
face a quick wash, has a simple breakfast and rushes to the four rubbish dustbins beside the gate of her living area. There she checks the waste left by her neighbours to make sure it is sorted correctly.
“Sorting rubbish will improve the environment and it only takes a minute,” Wang said. “I want to help my neighbours develop good habits.”
As Wang spoke, an old man came by and threw a plastic bag full of rubbish into the dustbin marked “recyclable”.
“Hey, please, there are some orange peels(皮)and fish bones in your bag, so they are supposed to be put into the dustbin marked ‘kitchen waste’,”Wang told him.
Learning the old man was in a hurry, Wang let him go, opened the bag herself, picked out the kitchen waste and threw it into the right dustbin.
Wang has been doing this every day from 7:30 a. m. to 9 a. m. and from 6 p. m. to 8 p. m. since 10 March. She says people usually go downstairs and throw out rubbish at this time.
