October 16, 2021, is World Food Day, to raise awareness among the public about food waste. Chinese artist Forest Young used 500 grams of gold to create 1000 grains of pure gold rice, each of which is made of pure gold and has the same shape and size as real rice. Then throw them one by one into various corners of Shanghai, such as the Huangpu River, trash cans, sewers, and subways. And declare: We don't waste food, we only waste gold!
