Singles’ Day is a day for chinese people to celebrate and socialize their pride on being single. It was started in 1993 in Nanjing by a group of bachelors. It is celebrated on November 11, for the numerical date “11/11” as it shows four “singles”. In 2009, Alibaba (Asia’s largest online ecommerce tech company) turned it into an online shopping event by offering massive discounts on its online marketplace, Tmall, for only 24 hours. The event has now become the largest offline and online shopping day in the world with sales of over US$25.4 billion in 2017.
