For every flower gifted on Valentine's day, someone is treating themselves to a box of chocolates. It’s a common practice to spend money on yourself on days like Valentine’s Day, and many stores offer discounts and promotions to capitalize on this trend. But China has an entire day devoted to single people. Every November 11th the aptly-named “Singles Day” inspires millions of singles to participate in special events, eat themed candies, and—above all—shop. It’s the largest online shopping day in the world, but unless you’ve lived in China, you probably haven’t heard of it.
