Recently, a 'love fridge' was set up on a street in Yuyao City, Zhejiang Province, offering free ice water and popsicles to outdoor workers enduring the heat. A delivery driver took a popsicle for his daughter, and returned the next day to restock the fridge with three boxes of mineral water. Such a relay of kindness is expanding, with more and more people replenishing the fridge's supply.
