"Double Eleven," also known as Singles' Day, is an annual shopping event held on November 11 in China. It was originally created to celebrate single individuals but has evolved into the world's largest online shopping festival. Retailers offer significant discounts, attracting millions of consumers to participate in massive sales. The event was popularized by Alibaba, a major e-commerce platform, which launched its first Double Eleven sales in 2009. Since then, it has grown exponentially, with billions of dollars in sales generated each year. The day has become a global phenomenon, influencing shopping trends beyond China.
