Since childhood, I’ve had a keen interest in toy exchange – I always saw it as the start of a new friendship. Nowadays, my hobby has shifted to exchanging second-hand clothes, but the sentiment remains. This story is particularly relevant to my 12-year-old niece, an only child living in a big and often lonely city, who has amassed a large collection of toys. The issue of toy waste is critical to the wider community in Beijing, where an alarming 63% of toys are discarded annually. In just one district alone, 540 families are grappling with this problem.
